Why does coffee not have any affect on me?

[whiterabbity]

I don’t think I have ADHD, I don’t have any of the symptoms. But for some reason, coffee does not stimulate me at all, no matter how much I have. I can have one at 10pm and fall asleep shortly after. Is anyone else like this??

Same, sadly. Coffee does give me a little mood boost but not extra energy. I can sleep straight after drinking a cup too. Always been this way.

It's never affected me, nor my DH, we sleep like logs despite having a coffee before bed.

This is true of lots of people - it's really not unusual. The effects of caffeine are massively overstated by most people, to be honest.

I have adhd and before being medicated it had zero effect on me, to the point if I had a big redbull I’d feel sleepy. I could have multiple a day and it wouldn’t have an effect the only thing I noticed was the headaches after a few of them, but no wide awake buzzing feeling. I craved the sugar and sweetness from it. Now I’m medicated I don’t crave anything sweet at all and haven’t had any caffeine except an iced frappe the other day at my SIL and I was WIRED all night. Didn’t give me a buzz just kept me awake annoyingly late 🤨

The only thing caffeine has an effect on for me is my bowels!!

Caffeine stops (temporarily) adenosine being absorbed by the brain. It doesn't work on everyone.

It’s caffeine, not crack.
