I'm probably your complete opposite on this lol.

I don't know how tolerance plays into this, but I drink like 1L or more of coffee a day, and have done so for more than a decade, and I have never felt any difficulty falling asleep.

Well, besides some reluctance during weekdays because I just don't want the next day to arrive, because of work, so I sometimes just go to sleep later and suffer the consequences for the next following days; but during long vacations (1-2 consecutive weeks long) it's all good, even with little to no variation on how much coffee I drink or the times I wake up and go to bed compared to outside vacation, so I think the problems are not related to coffee (at least not too much).

I don't even feel "awoken" when I drink coffee, and it's always weird when I read people saying they drink coffee to feel more awake. Or to get more energy, or something.

So I don't think I've ever drank it for any reason other than the taste. Caffeinated or decaffeinated; a 325ml mug full of undiluted?[1][2] espresso, vs milk coffee; literally no (perceivable) difference to me other than taste.

If anything, when I want to "stay awake", I try to drink something very sweet. It doesn't "wake me up" like I hear people say with coffee, but it very slowly takes away just a little bit of sleepyness.

[1]: Probably the wrong term. But I mean, taking a coffee "capsule", serve with the recommended "size" (which is very small), and repeat with more "capsules" until the mug is full. I don't do this very often though.

[2]: And yes, I want to learn how to make myself a coffee that tastes almost as good, so that I can stop polluting with these disposable capsules.

Do you have an attention disorder? I know from some people they experience caffeine differently. Although the mechanisms are beyond me.

Diagnosed ADHD person here. Among my acquaintances I’m known as a person who will accept coffee any time off day when I come visit. I don’t that because I really enjoy the flavor off coffee and it doesn’t seem to affect my sleep.

Anecdotally, I’ve had conversations with more than 50 people who say caffeine does not affect them who likely have ADHD or some kind of attention disorder.

For example, I was at a gas station this weekend buying coffee during a small road trip. The cashier and I we’re making small talk that it was early and I wanted my morning coffee, they said oh caffeine doesn’t affect me. When I hear something like that I usually ask if them if they have ADHD and they’ll typically respond with a yes.

There is definitely bias in my non-scientific survey, I only ask people who make the comment about caffeine not affecting them.

Do you mean it doesn’t affect their sleep? I remember the first time I tried coffee and the effect was profound, like my brain wasn’t working properly before that moment. I have also been diagnosed with ADHD, but I am affected by caffeine so maybe that’s a misdiagnosis. I also have huge variation over my life where I can sometimes handle 6+ cups without issue and other times half of a Diet Coke will send me spiraling into anxiety. It seems like it has to do with my stomach or baseline levels of anxiety, definitely worse after some sort of trauma. Maybe just a comorbidity that complicates things

I also have ADHD (though the lesser inattentive variety) and caffeine affects me. There are dozens of us!

Eh, I'd say "probably not", but I really haven't tried going to a doctor to check.

I also drink a lot of coffee. I notice the feeling, but it's slight. I rarely drink energy drinks anymore so if I drink a Red Bull I do feel it. My caffeine tolerance is pretty high. I can drink coffee with dinner and sleep fine an hour later.
