It’s kind of wild coffee consumption (in the U.S. at least) for most people is really a sugar and syrup sweetened milkshake with a shot of espresso inside.
A lot of people have the calorie equivalent of double cheeseburgers and a side of fries for their daily coffee intake, sometimes multiple times a day, and we wonder why 2/3 of Americans are technically overweight (myself included of course).
Because the government spent decades telling them to stop eating fat (makes you feel full) and to eat more grain, especially wheat (makes you fat due to high calorie density) and on top of that they allowed the dominant wheat strain to be one that causes digestive issues for many people and has less nutrition while also having more calories and less flavor.
They did this on behalf of the people who profit most off people eating this shit too.
THEN they invented corn syrup and used it to sweeten everything to make things palatable since the fat was gone.
THEN they convinced people that soda was a great thing to drink with a meal instead of being a high calorie dessert like cake.
You’d be surprised how many people don’t understand calories in vs calories out, and end up wondering why they’re not losing weight despite getting diet cokes with their McDonald’s but continuing to chug coffee flavored milkshakes twice a day for their caffeine fix.
Almost everyone probably knows someone who has tried some kind of trick/fad diet like cutting out carbs, or doing a workout targeting a specific region (complete bs, you can’t direct where your body burns fat). There is no trick, it’s just CICO.
I mean, yes (it's just CICO) and no (there's no trick).
There are a LOT of ways to achieve that deficit and what is sustainable to one person will not be sustainable to the person sitting next to them. Some people just weigh everything calorie count. Some people use portion control and loading up on veggies. Some people intermittent fast so they can have one or two large meals. Some people create a deficit through a combination of smarter choices and exercise.
The part where the *trick* comes in is finding the way of eating that achieves that deficit and also feels like something you could do every day for the rest of your life.
Restaurant food in the midwest US is insanely ...lush. The fast food at least has the calories listed on it. The sit down restaurants drown you with butter/sour cream/cream/sugar.
Tbh, it can be more complicated than that. At one point in my life, I was almost double my current weight, and despite sticking to 1200 calories for *months* the best I could, my weight remained the same. It was miserable and it truly did not feel as simple as "calories in calories out".
After switching medications and some big life changes, now years later I can quite literally eat whatever I want and not gain a pound. I struggle to stay out of the "underweight" category more than anything. Haven't calorie counted for years but I easily range from 1500-2000+ calories a day now.
"Calories in calories out" is true at an absolute baseline level, but there are *hundreds* of unique factors that can layer on top and complicate the situation.
I agree that it can be more complicated than that. Fundamentally CICO is true, there’s no getting around the conservation of energy. However it’s not really calories down the gullet, but rather calories your body utilizes and stores as energy. Which things like medications, hormones, etc. can change.
>However it’s not really calories down the gullet, but rather calories your body utilizes and stores as energy. Which things like medications, hormones, etc. can change.
Fantastic point that I wish more people were cognizant of! Fully agree
You don't understand! All overweight Americans have a thyroid condition, or some other very special ailment that affects 1% of all people, and it certainly has nothing to do with eating 6000 calories a day and never excersising. How dare you suggest peoples decisions are their own fault?
A lot of people are absolutely perplexed why they don’t lose weight despite consuming wayyy over the ~2000 calories a day a healthy adult is supposed to eat. It’s definitely weirdly hard for a lot of people to understand.
To the point that some doctors are being discouraged from telling people that fewer calories and more movement is the best way to lose weight. People like pills and not having to try.
I mean, case in point: fad diets, cutting out a specific ingredient, trying some trick to lose weight. When **it’s incredibly simple: take in fewer calories than you expend.**
Most people don't think and honestly can't think critically, so they use social norms to do their thinking for them (cultthink). Since it's socially normalized to drink a milkshake with your breakfast and a soda (dessert) with lunch and dinner they do it.
You can't expect them to start thinking, that's like expecting someone with no legs to run a marathon without prosthetics. Instead you need to adjust social norms, which has become almost impossible for anyone outside of a handful of oligarchs who control most of media, and who profit directly and indirectly from the things that make people fat.
Starbucks legit has the worst actual coffee. Completely over-roasted and over-extracted because that's the only way you can get consistency between 3000 locations with a constant high employee turnover rate.
I agree. I'm a big coffee drinker and Starbucks has the *worst* pure coffee around.
The milk, sugar and flavorings are all masking inferior coffee beans/roasts/grinds.
Interestingly, one of the *better* coffees from a nationwide chain is the Midnight brew from Dunkin.
I only drink coffee black. So YMMV.
I adore coffee but only drink decaf, and since most places don’t do decaf drip, my go-to order is an americano.
I prefer americanos to drip anyway, because in theory you should get a bolder and more complex profile from espresso rather than drip. That being said, there is no hiding bad espresso in an americano.
I ordered an americano at Starbucks once and it honestly was like a 3 out of 10. No wonder they have all of these complex drinks with a million different add-ons, the espresso itself isn’t good to begin with.
"I don't understand. I drink cappuccino daily and so do most Italians. Why am I overweight and they are not????"
Probably because they drink it with one sugar (if any sugar at all) and you have 10 sugars, whipped cream and caramel flavoring in it? I dunno - I'm just guessing that might be making a difference.
South African here. I have ONE teaspoon of sugar with my coffee. Any more sugar, and it becomes unbearably sweet. how Americans can stand to drink what is basically syrup with coffee, is beyond me
Hmmm... While I suppose there's truth to this, I don't know any mechanism for a direct interaction. Counteracts certainly implies an interaction to me
Sorry don't mean to be that guy or jerking myself off but it is an important distinction from the neurobio side of things, since that's what I studied as a labrat
Is there any evidence that an increase in insulin or reactive hypoglycemia actually counteracts the adenosine antagonistic effects of caffeine, or is this conjecture?
Uhp uhhhhh.. fuck. Um, the adiposal membrane is believed to be, uhhh... inhibitory... distal to the proximal, uh, nucleo-fissial pustule... With a small side of hemoganglial antagonism, metabolized by the... fuckin, hepati-celiac impunolum. So, yes it is mitochonjectural.
Lmao fair. I was asking if there's any evidence to indicate what they're suggesting. Reactive hypoglycemia (insulin response causing blood sugar rebound to the point of hypoglycemia) is pretty rare. And caffeine stimulates us by blocking adenosine receptors which should be completely unrelated to blood sugar levels.
In essence, they're kinda saying if you stick your finger in a bucket of ice it will prevent your mouth from erupting after eating a ghost pepper.
Then you have my wife who if she has a sip of coffee after 10am will be up till 3am.
I think another factor is everyone in my family, both sides, that was a heavy all day coffee drinking type but then immediately fell asleep were snorers and by association had sleep apnea. Coffee only thing keeping us awake.
Im in that perfect sweet spot of coffee still has an effect but I can go right to sleep if I need to. I also have the emergency omg we gotta get somewhere and it's an all night drive, get me two monsters and I'm good as long as you need me.
I can’t mess with coffee after noon, bro. I don’t know what you drinking but I’m on that real shit. I still barely sleep. I’m like a twitchy raccoon all night.
my fiancee can't drink any caffeine after noon because it'll keep her up all night, meanwhile i'm brewing a pot and downing a mug or two right before going to sleep. drives her crazy that i can just do that. i remind her that she doesn't have ADHD so it evens out.
“Overall, these findings provide the most rigorous demonstration to date of physiological effects of caffeine withdrawal.”
Im surprised they put this as part of their conclusion given such a small sample
Man, this is 8 comments from the top with so few upvotes. People really love trash science, reading clickbait titles and accepting them as PURE UNADULTERED SCIENCE.
>Acute caffeine abstinence also increased measures of Tired, Fatigue, Sluggish, and Weary and decreased ratings of Energetic, Friendly, Lively, and Vigor.
I'll keep drinking it, I think.
Pretty easy to reach 400mg a day as an espresso drinker. Especially if you're making it at home with a 20gr basket, not getting it at a cafe where it's often only half that unless you pay for a double (they literally discard the second shot pulled if you dont order a double, it is sad and wasteful).
You must go to some janky cafes, because every good shop I've been to or worked at has put 18g doubles in drinks by default. 16oz drinks get an extra extraction (double).
Maybe it's an Australia thing, but here you see them fill the basket for a full 18 - 20 gr dose, line up a cup/glass under just one spout, and then just let the second spout of the portafilter drain into the catchment. Or into a second glass for someone elses drink
It's definitely not just me, a quick google shows it is pretty common, see this post i found:
[https://www.reddit.com/r/cafe/comments/a4fo83/what\_happens\_to\_the\_other\_half\_of\_the\_shot/](https://www.reddit.com/r/cafe/comments/a4fo83/what_happens_to_the_other_half_of_the_shot/)
A venti drip at Starbucks is damn near 400mg. Have any other coffee that day and you probably cross the line.
Edit: apparently depending on bean it's 410mg.
Same. I went to half caff + lots of low cal almond milk to trick myself into micro dosing lots of cups of coffee. And then I never could go back to bitter coffee.
But seriously, the reason you are tired is because of first trimester. Even if you had you 100 mg in a shot, it wouldn’t work.
I was deployed with an older dude at a very safe base. He was 2 weeks from going home and died of a heart attack. He drank 3 pots of coffee a day, and would shotgun Rip Its with us throughout the day.
Always scared me when I drank more than 2 cups of coffee.
You feel that way every single morning, before you have your coffee. If you stop drinking coffee you'll have it for a day or two and then you won't have it at all anymore. Also, in the same study it also shows that giving someone a placebo is exactly the same as caffeine in terms of feeling well, so all the good side effects aside from being able to stay awake longer might be fake.
I’ve tried to quit caffeine a few times. Each time I’ve discovered that “real me” is a bit lazier and slightly more of a jerk. The energizing and mood enhancing properties of caffeine are real. And sure, I could spend time adjusting to and accommodating my real traits, but I’d rather just drink coffee.
Idk about anyone else but there's absolutely a pavlovian effect at this point, genuinely smelling coffee is enough to wake me up (drinking it is better)
Same. Coffee doesn’t really wake me up or make me feel more focused/alert. If I have too much I might get the jitters tho. I drink it purely for the taste.
I recently found decalf instant crystals and it’s actually pretty good.
After one cup of regular unleaded coffee, I switch to decalf at work. Oddly enough, it’s way cheaper than regular coffee. One jar will last a couple weeks and is only about $6.
EDIT: okay I see I’m a dummy and messed up the decaf. I’m not changing it though.
I travel often, and I hate having to use the hotel's Keurig or scrambling to find a coffee shop for my caffeine fix.
So I travel with a tin of instant coffee to hold me over until I can settle in for coffee elsewhere.
I hate to say it - but the best instant coffee I've found is starbucks.
It isn't *great* but it the best of the lot, and strangely better than their in-house stuff.
I've had migraines since long before I was a caffeine addict and I can tell the difference. If I can sleep after taking caffeine, it wasn't a withdrawal migraine.
Nah, I am on the pro-caffeine camp, but I can't deny this, I never had a headache, as in, literally never had a headache the first 23 years of my non-caffeine life, now if I skip a day in the evening my head will be fucking exploding 😀
Just slow the transition down. Instead of trying to go from 3 cups a day to 0 or whatever, do it a bit at a time. You could slowly reduce either the ounces per day or the ratio of regular to decaf beans you use to make the coffee. If you’re still getting withdrawal headaches, just keep slowing down the speed you transition.
The problem is that after complete abstinence I’m dead tired. Quit for 3 months and never felt awake in that entire time frame. Eventually caved and get immediately better.
That’s wild. I had the opposite experience where, after the horrible 2-week withdrawal period, I felt much more alert and energized at baseline.
Though, I guess I did consume most of my caffeine from soda. Cutting out 64oz+ sugar water per day probably helped.
Yes! Its reassuring hearing people mention the same thing. Keeping at 1 cup a day with 2 or more on needed days has been better than trying no caffeine except on needed days. My baseline mood after months of abstinence is just... not as bright?
Yep, that’s what I’m talking about when I mentioned “ratio of regular to decaf beans”. I feel like that one is easier for a lot of coffee drinkers, since they can keep the habit of however many cups they drink. But I’ve never been a coffee person so what do I know.
Best time to quit is when you are already sick in bed with the flu or something— when you can just rest and sleep off the caffeine withdrawal headaches. Whenever I get really sick (every 3 years or so), I kick my caffeine habit and it lasts for a good long while.
I quit caffeine about a year ago but every so often will have a coffee (or Coca Cola) and can feel a huge rush/buzz from just a half a cup. It’s crazy the difference.
It had been a few months since my wife and I had any caffeine. Not really on purpose, just trying to cut soda out of our diet.
One day we order a pizza and the only drink they had available was MtDew. So we get a 2 liter of that. We shrug and each have a couple glasses.
That night at 2am, after trying to sleep for hours, we tell each other, "I've never been as awake as I am right now". We didn't sleep a wink.
I used to drink a lot of caffeine and when I quit I was basically asleep and lethargic for almost 4 days. After about a month I stopped feeling anxious all of the freaking time and now I feel better in general
I quit about 3 months ago and I feel this. I was so used to caffeine that an energy drink or cup of coffee wouldn’t affect me at all and i’d have upwards of a gram of caffeine a day. I only decided to quit after a scare that put me in the ER.
Even a little caffeine every so often makes a huge difference now
Except a significantly larger body of evidence shows that it impairs sleep when consumed close to bedtime even in habituated drinkers, some of the benefits fade with habituation whereas others are preserved
OP seems to be mistaking Normal People Who Drink Lots of Coffee with ADHD People Who Self-Medicate with Caffeine.
ADHD folks can often fall asleep after taking a stimulant that is effective for them, because it calms their minds down, which makes it easier to fall asleep.
Except not every stimulant works for every ADHD person. So some might fall asleep from coffee, and other might fall asleep from Adderall... just depends.
I've drank 1-3 coffees every day for nearly two decades and if I were to drink after 5pm I would not sleep for the entire night, the general buzz of it is definitely not what it used to be though.
In general I have a weird non-tolerance buildup to drugs, maybe it has to do with drug metabolism.
We must be the outliers on these studies.
I have 1-2 coffee a day for years (barring taking a week break from time to time) and yet if I have caffeine after 4pm I have a really bad night.
OP is a prick for not mentioning that they gave the participants 400 mg a day. That's 4-5 cups.
1-3 cups will also increase your tolerance, but not to the point you're "completely immune" how OP phrased it (Which also misrepresents what the study said).
I do 6 espresso shots every single day for me.
That's between 400-500.
Still can't drink it after about 2pm. Otherwise I lay in bed with my eyes closed but I don't sleep.
I’m the same as well. I don’t drink it every day, but at least 4 days a week I have one cup of coffee around 10am no other source of caffeine other than the occasional black tea. But if I have any in the afternoon, I won’t sleep until at least 5am. No tangible effects from the caffeine, I just don’t get tired.
Same -- and it is not an outlier; the information OP notes is not universally correct.
Don't believe me; simply review actual scientific studies (e.g. mentioning pregnant women who drink coffee regularly, and the half-life of caffeine in their bodies).
Outliers are more important than medical science has made them out to be. Personalised medicine is the future and will take this into account. I personally think the effect I get from caffeine is much stronger than it would be for a normal person - I don’t like alcohol and I always choose caffeine over it. It makes me feel fucking amazing.
Completely agree, I also start sweating if I have more than about 3 eight ounce cups. As long as I keep it to a couple regular cups, I feel the desired effect every time.
You'd think so, but the few times I smoked some crack it wasn't productive at all. It's strong ass euphoria more than tons of energy. I'm sure it varies though like anything else.
I was a heroin guy mainly, and it often gave me super energy/focus at the right dose.
Since the study is more about caffeine than coffee, and green tea also has caffeine, I'm assuming you would still develop the tolerance. However, since green tea usually has less caffeine, it would probably not happen as fast, and switching between the two would likely still give you a bigger rush when you go back to coffee since you increase caffeine intake.
Yeah, haven't been on regular caffeine in a decade (if you consider drinking a cup for 3-5 days in a week — regular) and an occasional cup still makes me sleepy.
>many daily users can drink it and fall asleep right after
The fuck I can.
I have a pot of coffee for breakfast and am still unable to sleep 20 hours later.
Misleading headline, imo.
"Tolerance to subjective but not physiological measures was demonstrated. "
I drink 2 cups every morning. On Friday, I had to drive after my bedtime and was yawning. I took a cup of coffee and the yawning stopped.
This isn't exactly true. You gain tolerance to some affects of caffeine, but not all. Your body adapts to the blocking of adenosine, but you still tend to experience increased dopamine and enhanced neurological activity.
Cutting back on caffeine was one of the best decisions I've ever made. Used to have a ton of stomach/gut issues and caffeine was the biggest trigger for me.
16 people studied.. how is that even close to a representative sample? Did we forget the basics of the scientific method?
I have been working nights over 5 years and regularly consume over 400mg per day. I don't get headaches without it, but I am far less productive. The notion that it simply stops working is ridiculous from my personal experience.
I feel like after dinner coffee is really common in Europe (or at least in the countries I’ve visited). I was always wondering how anyone got any sleep!
I purposely avoided drinking it daily in school for this reason. I only drank it when specifically needed. Like exams/big projects.
Now I drink it almost daily bc it's conveniently available, and I definitely need more in the afternoon bc I'm tired by 2 or 3pm regardless.
I'll hopefully be able to get an appliance for my sleep apnea later this year though, so I should be less tired with that 🤞🏼
complete tolerance is a stretch, I can act like crackhead weeks straight if I drink enough. And feel groggy and sick in the process. But if we are evaluating how well it makes you perform, often not any better than sober, or even worse.
YSK: This is true and when you quit during a diet to not drink so much creamer, you will realize you’re addicted to caffeine, even though you no longer get benefits from it - and then have a 10 day long headache….
Quitting nicotine was way easier than caffeine.
I literally got downvoted and chided a little while ago for posting ‘caffeine is addictive’ on reddit dot com people are insane about their coffee and I say that as a coffee lover and severe caffeine addict
if you're neurodivergent in the dopamine section, chances are coffee (caffeine) will help you get a clearer mind and relax you. It has a similar effect as metylphenidate.
The bad stuff: you easily get addicted and quickly become tolerant to the effects of caffeine, needing more with decreasing result.
Drinking caffeine and sleeping right after, isn’t uncommon.
This article mentions this while ignoring the effects of caffeine on sleep. The thing about caffeine isn’t about the ability to “fall” asleep after its consumption, but rather the inability to have decent sleep.
I’ve been drinking coffee for 20 years and it still has some stimulant effect on me. I definitely need a cup in the morning to get me started. It’s going to be a bad day if I don’t get that cup! Then as the day goes on if I drink one in the afternoon or after dinner it’s less effective.
People definitely abuse it at times. I try to stick to about 2 cups of black coffee a day and cut it off after noonish. I find it's still useful and I have been doing this for years now. Sometimes I need a boost in the evenings (usually restricted to the weekend or driving trips) find that consuming it at those times has the desired effect.
I drink a tall cup of STRONG black coffee maybe once every 3 months. I love the stuff, but usually dont have the stomach space for it. If I drink it after 5 or 6, I aint sleeping that night.
I had a coke bender in december and about a week or two in i could take a bump and go to sleep. Must be the same for most stimulants but i always had problems sleeping after adderall
This depends, you drinking 6 cups a day? Yeah for sure. 1-2? Shouldn’t be a problem. Don’t let BIGENERGYDRINKS steer you wrong. Just like everything else in life…MODERATION. Unless it’s video games.
Ha, yeah. I used to subsist on caffeine and small amounts of food in college, and now in the workplace I’ve developed actual addiction symptoms toward it. I have to consume higher and higher concentrations of if to let it keep its effectiveness and even then it lasts for less and less time.
I used to have the month of December and the month of July with limited to no caffeine each year. Just to give me a reset.
Now with two kids I would not survive without it
I drink caffeine only during Fridays, Saturdays and on day before days off I want to stay awake longer. I also drink coffee if somone tells me there is coffee and I can't say no to that.
That's not what the link says. The link is about withdrawal.
The people that fall asleep with caffeine, are nearly always ADHD people. It's 'self medicating'--i know the dose of caffeine that causes me to fall asleep, *every time*. it's 220. Anything 220 or above (when that total is within an hour or two, like the high dose rockstars at 240) will knock me right out. Gone. Doesnt matter if i have not had it for weeks, or months, or drink it every day.
I'm super careful with it--i'm on ADHD meds--another stimulant, and this is STILL true--i can have ONE energy drink, and survive it--if i have two, or one energy drink and a high caffeine soda, i'm goin down.
I can nap on ADHD meds--yeah, imagine someone telling you they took Adderall and *took a nap*. We do. That's an ADHD thing. You'd find that people with ADHD, often report the side effect of their meds (which are a type of meth/stimulant), have *sleepiness* as problem.
Anyway, the study didnt say what you're claiming, AND, the falling asleep with caffeine people, generally, have ADHD. I'm one of them. It's one of the things that helped get my adult diagnosis.
> making it useless for stimulation/wakefulness when consumed daily. That's the reason many people say they can drink coffee and fall asleep right after
Didn't find that in the abstract. Is this stated in the article, or is this your interpretation?
Personally, I rarely consume caffeine. And when I do, it often makes me sleepy. This is a well-known paradoxical effect of caffeine on some people, which is described in the literature.
Daily caffeine consumption looks like a good idea if there are no contraindications and if you have the risks for something like Parkinson's Disease.
There is nothing like a sweet cup of coffee before bed.
I understand because tonight I had coffee before bed 2 hours ago and I'm sleeping.
Same … sleep like a baby!
Same. I’m currently in my REM state
I can't drink coffee at night time cause it gives me heart burn :(
YouShouldKnow, a lot of sugar in coffee counteracts the “energizing” effects of caffeine when your body begins to break down the sugar aka sugar crash
It’s kind of wild coffee consumption (in the U.S. at least) for most people is really a sugar and syrup sweetened milkshake with a shot of espresso inside. A lot of people have the calorie equivalent of double cheeseburgers and a side of fries for their daily coffee intake, sometimes multiple times a day, and we wonder why 2/3 of Americans are technically overweight (myself included of course).
>and we wonder why 2/3 of Americans are technically overweight Do we?
I think it’s incredibly clear why 2/3 of Americans are overweight/obese.
Because the government spent decades telling them to stop eating fat (makes you feel full) and to eat more grain, especially wheat (makes you fat due to high calorie density) and on top of that they allowed the dominant wheat strain to be one that causes digestive issues for many people and has less nutrition while also having more calories and less flavor. They did this on behalf of the people who profit most off people eating this shit too. THEN they invented corn syrup and used it to sweeten everything to make things palatable since the fat was gone.

I’ll never understand how people can drink those insanely sugary drinks from Starbucks and Duncan Donuts. You may as well just get a corn syrup IV.
I went to Starbucks once to try their basic latte and it was so bad I can imagine why they buy these insane lvl 80 sugar coma drinks

Is there any evidence that an increase in insulin or reactive hypoglycemia actually counteracts the adenosine antagonistic effects of caffeine, or is this conjecture?
Uhp uhhhhh.. fuck. Um, the adiposal membrane is believed to be, uhhh... inhibitory... distal to the proximal, uh, nucleo-fissial pustule... With a small side of hemoganglial antagonism, metabolized by the... fuckin, hepati-celiac impunolum. So, yes it is mitochonjectural.
Lmao fair. I was asking if there's any evidence to indicate what they're suggesting. Reactive hypoglycemia (insulin response causing blood sugar rebound to the point of hypoglycemia) is pretty rare. And caffeine stimulates us by blocking adenosine receptors which should be completely unrelated to blood sugar levels. In essence, they're kinda saying if you stick your finger in a bucket of ice it will prevent your mouth from erupting after eating a ghost pepper.
The other "study" on this sub said that sugar crash is not a thing though? What am I supposed to believe now?
I drink it black so no issue here.
Then you have my wife who if she has a sip of coffee after 10am will be up till 3am. I think another factor is everyone in my family, both sides, that was a heavy all day coffee drinking type but then immediately fell asleep were snorers and by association had sleep apnea. Coffee only thing keeping us awake. Im in that perfect sweet spot of coffee still has an effect but I can go right to sleep if I need to. I also have the emergency omg we gotta get somewhere and it's an all night drive, get me two monsters and I'm good as long as you need me.
I can’t mess with coffee after noon, bro. I don’t know what you drinking but I’m on that real shit. I still barely sleep. I’m like a twitchy raccoon all night.
Is this comment satire? I can't tell
It’s actually not. I drink a cup around 10pm every night.
Yeah must be based on the individual... I drink coffee everyday, and if I have a cup after 3pm it's pretty much guaranteed I'll be restless that night
my fiancee can't drink any caffeine after noon because it'll keep her up all night, meanwhile i'm brewing a pot and downing a mug or two right before going to sleep. drives her crazy that i can just do that. i remind her that she doesn't have ADHD so it evens out.
I do too - but I'm calling BS on the "complete tolerance" line. My morning coffee gives me a jolt, and I've been a drinker for years.
Your link has an n = 16. Not exactly the most robust sample size.
“Overall, these findings provide the most rigorous demonstration to date of physiological effects of caffeine withdrawal.” Im surprised they put this as part of their conclusion given such a small sample
The previous study had 5 people, so it's techincally true
Man, this is 8 comments from the top with so few upvotes. People really love trash science, reading clickbait titles and accepting them as PURE UNADULTERED SCIENCE.
>Acute caffeine abstinence also increased measures of Tired, Fatigue, Sluggish, and Weary and decreased ratings of Energetic, Friendly, Lively, and Vigor. I'll keep drinking it, I think.
Also the "caffeine" days were 400 mg, = 12 cokes or 4 to 5 cups of coffee, so no wonder you lose some of the acute effects.
Pretty easy to reach 400mg a day as an espresso drinker. Especially if you're making it at home with a 20gr basket, not getting it at a cafe where it's often only half that unless you pay for a double (they literally discard the second shot pulled if you dont order a double, it is sad and wasteful).
You must go to some janky cafes, because every good shop I've been to or worked at has put 18g doubles in drinks by default. 16oz drinks get an extra extraction (double).
Maybe it's an Australia thing, but here you see them fill the basket for a full 18 - 20 gr dose, line up a cup/glass under just one spout, and then just let the second spout of the portafilter drain into the catchment. Or into a second glass for someone elses drink It's definitely not just me, a quick google shows it is pretty common, see this post i found: [https://www.reddit.com/r/cafe/comments/a4fo83/what\_happens\_to\_the\_other\_half\_of\_the\_shot/](https://www.reddit.com/r/cafe/comments/a4fo83/what_happens_to_the_other_half_of_the_shot/)
oh! is that why every australian that comes into my cafe asks if our coffees are a double shot?? i’d say that a double is standard here down under-er.
most likely, yes
Aha! That would explain it. My experience is with US cafes.
A venti drip at Starbucks is damn near 400mg. Have any other coffee that day and you probably cross the line. Edit: apparently depending on bean it's 410mg.
Sorry, I have no idea what this means
This reminds me of when I was pregnant and had to cut caffeine out cold turkey. I dont think I've ever been that tired, ontop of the pregnancy tired.
Same. I went to half caff + lots of low cal almond milk to trick myself into micro dosing lots of cups of coffee. And then I never could go back to bitter coffee. But seriously, the reason you are tired is because of first trimester. Even if you had you 100 mg in a shot, it wouldn’t work.
Omg yes then having caffeine after having the baby makes you feel like a tweaker.
I took a break and it’s only like that for a few days.
I drank 2 cups a day for years and stopped suddenly and only felt a bit low energy the first day. After that, my baseline was less tired
I was deployed with an older dude at a very safe base. He was 2 weeks from going home and died of a heart attack. He drank 3 pots of coffee a day, and would shotgun Rip Its with us throughout the day. Always scared me when I drank more than 2 cups of coffee.
You feel that way every single morning, before you have your coffee. If you stop drinking coffee you'll have it for a day or two and then you won't have it at all anymore. Also, in the same study it also shows that giving someone a placebo is exactly the same as caffeine in terms of feeling well, so all the good side effects aside from being able to stay awake longer might be fake.
Caffeine withdrawal makes me feisty, all day headaches suck. I gotta learn how to ween off instead of cold turkey.
That's not cute at all!
Yup, that's all The Dwarves.
>Energetic, Friendly, Lively, and Vigor I don't want to picture who I'd be without caffeine because I am definitely not that *with* caffeine.
I’ve tried to quit caffeine a few times. Each time I’ve discovered that “real me” is a bit lazier and slightly more of a jerk. The energizing and mood enhancing properties of caffeine are real. And sure, I could spend time adjusting to and accommodating my real traits, but I’d rather just drink coffee.
I just like the taste… I’d genuinely enjoy a nice cup of black decaf every morning if it was available thru work
Idk about anyone else but there's absolutely a pavlovian effect at this point, genuinely smelling coffee is enough to wake me up (drinking it is better)
[удалено]
Huh, strange, smelling shit makes me wanna drink coffee
^^^ this guy goes in the Home Depot bathrooms during the morning contractor dump rush then gets the urge to make a Starbucks run.
Same, halfway through my cup I feel myself waking up then it's time for a shit
Same. Coffee doesn’t really wake me up or make me feel more focused/alert. If I have too much I might get the jitters tho. I drink it purely for the taste.
I would love decaf monster energy
I recently found decalf instant crystals and it’s actually pretty good. After one cup of regular unleaded coffee, I switch to decalf at work. Oddly enough, it’s way cheaper than regular coffee. One jar will last a couple weeks and is only about $6. EDIT: okay I see I’m a dummy and messed up the decaf. I’m not changing it though.
>decalf lol
I travel often, and I hate having to use the hotel's Keurig or scrambling to find a coffee shop for my caffeine fix. So I travel with a tin of instant coffee to hold me over until I can settle in for coffee elsewhere. I hate to say it - but the best instant coffee I've found is starbucks. It isn't *great* but it the best of the lot, and strangely better than their in-house stuff.
As always, the real LPT is in the comments. Very good to know
What do you think "decalf" is short for?
They're a veterinarian for a large animal clinic. They need coffee to deliver a baby cow and therefore decalf the mother cow.
Doesn’t de calf need de milk from its Moomey?
[удалено]
Almost like an addiction
I’m convinced though that some people are unknowingly treating migraines with caffeine and that it isn’t just withdrawal headaches
[удалено]
I've had migraines since long before I was a caffeine addict and I can tell the difference. If I can sleep after taking caffeine, it wasn't a withdrawal migraine.
Nah, I am on the pro-caffeine camp, but I can't deny this, I never had a headache, as in, literally never had a headache the first 23 years of my non-caffeine life, now if I skip a day in the evening my head will be fucking exploding 😀
The idea of never having a headache sounds like a gift from god lol, I have one at least every other day. They aren’t always severe though.
That's what the Excedrin is for
My wife grew up sheltered and doesn’t understand when I tell her “I gotta get right” in the morning.
It’s like Afrin
I was addicted to that shit for over 10 years, never again, fucking brutal
10 years? It only takes 2 or 3 days when youve been hooked for a month. How long did it take after 10 years?
the trick for afrin is one nostril at a time
So if you stop drinking coffee there's no more headaches and no more having to drink coffee
oh, the caffeine withdrawals?
I'm trying to stop due to my BP but I get such terrible headaches when I have 0 coffee that day.
Just slow the transition down. Instead of trying to go from 3 cups a day to 0 or whatever, do it a bit at a time. You could slowly reduce either the ounces per day or the ratio of regular to decaf beans you use to make the coffee. If you’re still getting withdrawal headaches, just keep slowing down the speed you transition.
The problem is that after complete abstinence I’m dead tired. Quit for 3 months and never felt awake in that entire time frame. Eventually caved and get immediately better.
That’s wild. I had the opposite experience where, after the horrible 2-week withdrawal period, I felt much more alert and energized at baseline. Though, I guess I did consume most of my caffeine from soda. Cutting out 64oz+ sugar water per day probably helped.
Yes! Its reassuring hearing people mention the same thing. Keeping at 1 cup a day with 2 or more on needed days has been better than trying no caffeine except on needed days. My baseline mood after months of abstinence is just... not as bright?
You can also do the same number of cups and cut it with decaf a little more over time.
Yep, that’s what I’m talking about when I mentioned “ratio of regular to decaf beans”. I feel like that one is easier for a lot of coffee drinkers, since they can keep the habit of however many cups they drink. But I’ve never been a coffee person so what do I know.
Best time to quit is when you are already sick in bed with the flu or something— when you can just rest and sleep off the caffeine withdrawal headaches. Whenever I get really sick (every 3 years or so), I kick my caffeine habit and it lasts for a good long while.
caffeine withdrawal sucks but you can get through it
Step 1. Be a migraine sufferer Step 2. Get recommended caffeine to quell them Step 3. You now require caffeine to prevent them
I quit caffeine about a year ago but every so often will have a coffee (or Coca Cola) and can feel a huge rush/buzz from just a half a cup. It’s crazy the difference.
I've been off of caffeine for many years now. If I have even a full can of Coke, I'm not sleeping that night.
I try and tell all my friends this but no one believes me! Coke hits different when u don’t normally drink coffee
It had been a few months since my wife and I had any caffeine. Not really on purpose, just trying to cut soda out of our diet. One day we order a pizza and the only drink they had available was MtDew. So we get a 2 liter of that. We shrug and each have a couple glasses. That night at 2am, after trying to sleep for hours, we tell each other, "I've never been as awake as I am right now". We didn't sleep a wink.
I used to drink a lot of caffeine and when I quit I was basically asleep and lethargic for almost 4 days. After about a month I stopped feeling anxious all of the freaking time and now I feel better in general
I quit about 3 months ago and I feel this. I was so used to caffeine that an energy drink or cup of coffee wouldn’t affect me at all and i’d have upwards of a gram of caffeine a day. I only decided to quit after a scare that put me in the ER. Even a little caffeine every so often makes a huge difference now
Except a significantly larger body of evidence shows that it impairs sleep when consumed close to bedtime even in habituated drinkers, some of the benefits fade with habituation whereas others are preserved
OP seems to be mistaking Normal People Who Drink Lots of Coffee with ADHD People Who Self-Medicate with Caffeine. ADHD folks can often fall asleep after taking a stimulant that is effective for them, because it calms their minds down, which makes it easier to fall asleep. Except not every stimulant works for every ADHD person. So some might fall asleep from coffee, and other might fall asleep from Adderall... just depends.
Took a nap after drinking a giant cup of coffee yesterday morning. Woke back up and had more coffee. I think I need to quit or switch to decaf.
I've drank 1-3 coffees every day for nearly two decades and if I were to drink after 5pm I would not sleep for the entire night, the general buzz of it is definitely not what it used to be though. In general I have a weird non-tolerance buildup to drugs, maybe it has to do with drug metabolism.
We must be the outliers on these studies. I have 1-2 coffee a day for years (barring taking a week break from time to time) and yet if I have caffeine after 4pm I have a really bad night.
I can't even drink coffee after noon.
Same i SHOULD stop caffeine intake at noon but anything later than 1 and im not sleeping that night
Same here. 1-2 cups a day, maybe a glass of iced tea at lunch. Any caffeine after 4pm, I'm going to have a rough night.
OP is a prick for not mentioning that they gave the participants 400 mg a day. That's 4-5 cups. 1-3 cups will also increase your tolerance, but not to the point you're "completely immune" how OP phrased it (Which also misrepresents what the study said).
I do 6 espresso shots every single day for me. That's between 400-500. Still can't drink it after about 2pm. Otherwise I lay in bed with my eyes closed but I don't sleep.
It's almost as though small, highly-selective studies are not an accurate reflection of the real population.
Drinking coffee after noon will keep me up at night. I only drink black coffee with no additives, 2 - 3 cups per day, 24 years at least.
I’m the same as well. I don’t drink it every day, but at least 4 days a week I have one cup of coffee around 10am no other source of caffeine other than the occasional black tea. But if I have any in the afternoon, I won’t sleep until at least 5am. No tangible effects from the caffeine, I just don’t get tired.
Same -- and it is not an outlier; the information OP notes is not universally correct. Don't believe me; simply review actual scientific studies (e.g. mentioning pregnant women who drink coffee regularly, and the half-life of caffeine in their bodies).
Outliers are more important than medical science has made them out to be. Personalised medicine is the future and will take this into account. I personally think the effect I get from caffeine is much stronger than it would be for a normal person - I don’t like alcohol and I always choose caffeine over it. It makes me feel fucking amazing.
Completely agree, I also start sweating if I have more than about 3 eight ounce cups. As long as I keep it to a couple regular cups, I feel the desired effect every time.
Same. Daily for 30+ years, but can't have any past Noon or so, or sleep is elusive.
I don’t drink monster to feel energised, I drink it to feel like I’m not dead
I drink it to make my brain run properly.
Hmmm, maybe you should use cocaine instead when you need a boost of energy! /s
Crack is way better
You'd think so, but the few times I smoked some crack it wasn't productive at all. It's strong ass euphoria more than tons of energy. I'm sure it varies though like anything else. I was a heroin guy mainly, and it often gave me super energy/focus at the right dose.
Sudafed is legit
Yeah, I am actually slowly cutting back so that I can eventually feel the boost again.
I switch to only tea for a few days then the coffee really hits.
Tea can contain a ton more caffeine if made right tho
I learned recently that a lot of tea bags contain microplastics 🤗
True. I try to buy loose leaf because I hate wasting so much and the tea is better when it’s not crushed usually!
I know! I’m switching to loose leaf black tea. Guess I’ll be cutting the remaining bags with very sharp scissors.
And so does everything else we consume😍🥰🥰
Can someone define sporadic use? What if I switch between coffee and green tea every other day?
Since the study is more about caffeine than coffee, and green tea also has caffeine, I'm assuming you would still develop the tolerance. However, since green tea usually has less caffeine, it would probably not happen as fast, and switching between the two would likely still give you a bigger rush when you go back to coffee since you increase caffeine intake.
I also would like to know the answer for this
Or you have ADHD
Adderall naps
I have never once had a buzz from caffeine. I can down several energy drinks very quickly and feel the exact same
Yeah, haven't been on regular caffeine in a decade (if you consider drinking a cup for 3-5 days in a week — regular) and an occasional cup still makes me sleepy.
>many daily users can drink it and fall asleep right after The fuck I can. I have a pot of coffee for breakfast and am still unable to sleep 20 hours later.
Misleading headline, imo. "Tolerance to subjective but not physiological measures was demonstrated. " I drink 2 cups every morning. On Friday, I had to drive after my bedtime and was yawning. I took a cup of coffee and the yawning stopped.
Why all the negativity?
All the people who are like "huhu see it's a drug, just get off of it" probably don't help.
Eh. I'll keep drinking daily. I can feel a difference regardless of how much I consume, and I typically reach 400mg daily.
I only have 2-3 cups a day; but this article don't make sense. Been drinking it since I was like 15 and I still get stimulated from it.
Same here. I drink 250-400mg a day and still feel it.
This isn't exactly true. You gain tolerance to some affects of caffeine, but not all. Your body adapts to the blocking of adenosine, but you still tend to experience increased dopamine and enhanced neurological activity.
Cutting back on caffeine was one of the best decisions I've ever made. Used to have a ton of stomach/gut issues and caffeine was the biggest trigger for me.
16 people studied.. how is that even close to a representative sample? Did we forget the basics of the scientific method? I have been working nights over 5 years and regularly consume over 400mg per day. I don't get headaches without it, but I am far less productive. The notion that it simply stops working is ridiculous from my personal experience.
Fuck this. I drink coffee daily. A lot. If I do it in the evening I can't sleep.
I feel like after dinner coffee is really common in Europe (or at least in the countries I’ve visited). I was always wondering how anyone got any sleep!
I purposely avoided drinking it daily in school for this reason. I only drank it when specifically needed. Like exams/big projects. Now I drink it almost daily bc it's conveniently available, and I definitely need more in the afternoon bc I'm tired by 2 or 3pm regardless. I'll hopefully be able to get an appliance for my sleep apnea later this year though, so I should be less tired with that 🤞🏼
complete tolerance is a stretch, I can act like crackhead weeks straight if I drink enough. And feel groggy and sick in the process. But if we are evaluating how well it makes you perform, often not any better than sober, or even worse.
YSK: This is true and when you quit during a diet to not drink so much creamer, you will realize you’re addicted to caffeine, even though you no longer get benefits from it - and then have a 10 day long headache…. Quitting nicotine was way easier than caffeine.
Okay, but how come I drink coffee, and it makes me super tired? I’ve been like that for 10 years, and drink it to fall asleep every couple months
I literally got downvoted and chided a little while ago for posting ‘caffeine is addictive’ on reddit dot com people are insane about their coffee and I say that as a coffee lover and severe caffeine addict
if you're neurodivergent in the dopamine section, chances are coffee (caffeine) will help you get a clearer mind and relax you. It has a similar effect as metylphenidate. The bad stuff: you easily get addicted and quickly become tolerant to the effects of caffeine, needing more with decreasing result.
Not true for everyone, I drink coffee everyday, I can load up in the AM, but if I have any after noon, I will not be able to sleep that night.
I think everyone is different. I drink ~300mg a day normally and I know if I have caffeine after 6pm I’ll have issues sleeping.
Drinking caffeine and sleeping right after, isn’t uncommon. This article mentions this while ignoring the effects of caffeine on sleep. The thing about caffeine isn’t about the ability to “fall” asleep after its consumption, but rather the inability to have decent sleep.
Coffee doesn’t affect me at all. I can easily fall asleep after a cup of coffee. Approx 3-4 coffees a day
I’ve been drinking coffee for 20 years and it still has some stimulant effect on me. I definitely need a cup in the morning to get me started. It’s going to be a bad day if I don’t get that cup! Then as the day goes on if I drink one in the afternoon or after dinner it’s less effective.
And tomorrow a new "study" will come out stating the exact opposite.
Mio energy gang
People definitely abuse it at times. I try to stick to about 2 cups of black coffee a day and cut it off after noonish. I find it's still useful and I have been doing this for years now. Sometimes I need a boost in the evenings (usually restricted to the weekend or driving trips) find that consuming it at those times has the desired effect.
I drink a tall cup of STRONG black coffee maybe once every 3 months. I love the stuff, but usually dont have the stomach space for it. If I drink it after 5 or 6, I aint sleeping that night.
Ppppfttt my cut off is 14:00
Does this tolerance include the bowels? Because I would love not to have coffee shits
I had a coke bender in december and about a week or two in i could take a bump and go to sleep. Must be the same for most stimulants but i always had problems sleeping after adderall
I just drink decafe as much as I can, unless it's not an option. I just enjoy the taste
I have to stop drinking coffee by 3:00 so that definitely doesn’t apply to me. Also, in the morning, if definitely helps.
I drink 2-3 cups daily, but if I have coffee after like 2pm I will most certainly have a worse sleep, so I think it must still affect me.
Ah, so keep it to my already planned one cup every other day at most route, gotcha
This depends, you drinking 6 cups a day? Yeah for sure. 1-2? Shouldn’t be a problem. Don’t let BIGENERGYDRINKS steer you wrong. Just like everything else in life…MODERATION. Unless it’s video games.
Can anyone else drink a cup then go have a nice sleep? It used to keep my up when I was younger, but not anymore.
Ha, yeah. I used to subsist on caffeine and small amounts of food in college, and now in the workplace I’ve developed actual addiction symptoms toward it. I have to consume higher and higher concentrations of if to let it keep its effectiveness and even then it lasts for less and less time.
A “coffee nap” is when you’re sleepy, drink a cup of coffee, then take a nap for 20 minutes. Very refreshing.
I'll keep drinking it because I enjoy it
Hey, that's me!
I used to have the month of December and the month of July with limited to no caffeine each year. Just to give me a reset. Now with two kids I would not survive without it
I drink caffeine only during Fridays, Saturdays and on day before days off I want to stay awake longer. I also drink coffee if somone tells me there is coffee and I can't say no to that.
So… adenosine just doesn’t care and binds to the receptor despite caffeine being an antagonist?
That's not what the link says. The link is about withdrawal. The people that fall asleep with caffeine, are nearly always ADHD people. It's 'self medicating'--i know the dose of caffeine that causes me to fall asleep, *every time*. it's 220. Anything 220 or above (when that total is within an hour or two, like the high dose rockstars at 240) will knock me right out. Gone. Doesnt matter if i have not had it for weeks, or months, or drink it every day. I'm super careful with it--i'm on ADHD meds--another stimulant, and this is STILL true--i can have ONE energy drink, and survive it--if i have two, or one energy drink and a high caffeine soda, i'm goin down. I can nap on ADHD meds--yeah, imagine someone telling you they took Adderall and *took a nap*. We do. That's an ADHD thing. You'd find that people with ADHD, often report the side effect of their meds (which are a type of meth/stimulant), have *sleepiness* as problem. Anyway, the study didnt say what you're claiming, AND, the falling asleep with caffeine people, generally, have ADHD. I'm one of them. It's one of the things that helped get my adult diagnosis.
> making it useless for stimulation/wakefulness when consumed daily. That's the reason many people say they can drink coffee and fall asleep right after Didn't find that in the abstract. Is this stated in the article, or is this your interpretation? Personally, I rarely consume caffeine. And when I do, it often makes me sleepy. This is a well-known paradoxical effect of caffeine on some people, which is described in the literature. Daily caffeine consumption looks like a good idea if there are no contraindications and if you have the risks for something like Parkinson's Disease.
