I drink a small cup in the morning (like 250 ml) and 1-2 Moka pot espressos (like one shot). This typically happens between 7-10am. No more coffee after that most of the time. I like to keep it in the morning routine with breakfast. Green tea and water in my afternoons.

Personally, I don't feel any kind of "drug like" effects from this routine. I wonder about the strength of coffee people are drinking and the effects of drinking throughout the day rather than just the morning.

Anecdotally, during grad school I drank more per serving and throughout the day, and I certainly felt quite different than my current routine.

Like most things, I think people need to find some moderation/balance.

It's less about the strength of coffee than about your metabolism. I used to be unaffected by caffeine, and now it takes a few sips in the morning to mess with my sleep in the evening - sth that started happening in my twenties I believe, possibly liver-related.

Interesting, do you have any good links for this?

I can have a coffee a bit before bed if I really want. I also used to think I had a "high metabolism", but don't say that anymore since it comes off as kind of bogus.

		Unfortunately no. It's my inference, given that 23andme didn't find any genetic indicator (CYP1A2) for slow metabolism, which is in line with my experience I got more sensitive over time. So it must be some other mechanism that diminished enzyme production. Some of my liver (were those enzymes are produced) values were elevated over the last few years for no good reason, and I suspect the two could be related. It's a bit annoying, as I'm reacting to trace amounts of caffeine in coffee, tea or chocolate, but I'm more worried about all the other, possibly carcinogenic, environmental toxins my liver won't be able to filter out.
