People who think they’re 100% fine if they drink it before 2pm should check out how half life works. Not the game, the pharmaceutical concept. It’s super interesting.
Since it compounds, if you drink one cup in the morning, you will still have roughly 13% of that caffeine in your body at midnight. Both from the morning coffee, and the dregs over the last week. And that’s if your body processes it at an average speed; some people have a long half life of 10 hours, and the math gets crazy. You end up with like 40% of a coffee in your blood at midnight, and it’s a wonder why you can’t sleep!
Unless your brain gets a calming and mellowing effect from caffeine. Many ADHD people have that. Personally, I sleep very well to better with a little bit of caffeine but I can drink a Bang or other high caffeine energy drink and still zonk out without any struggles and sleep comfortably. It doesn’t stop my sleep, but can help me be awake if I want to.
(Half life still exists, I’m just talking about the whole “can’t sleep with caffeine” thing)
Same here for the most part, and I’ve been told a few times that it might be a sign of ADHD. I also have a low resting heart rate (low 40s), and I wonder if that plays a role.
I used to have barychardia too but only in the low 50s. Got it down to 30 once during an experiment in my oceanography class. That was actually kinda painful.
When I was running quite a bit, my resting heart rate dropped into the 30s in the early morning hours (while sleeping). I can’t say that I’ve experienced 30 with my eyes open though - that had to be an interesting feeling.

Adderall too. My buddy with ADHD would take his right before a nap lol
