In my experience, this is common among people with ADHD (myself, friends with ADHD, family with ADHD, psychologist’s patients anecdotal evidence). YMMV

I have adhd too, but cannot use stimulant medications (they are too strong). I've had to use non-stim meds.

What if long term caffeine use causes some of the adhd symptoms? It interesting to ponder because if I stop using caffeine for a month, some of my adhd symtoms go away completely. I've done stints of complete caffeine breaks, content consumption breaks (one week or more without screens) and I felt amazing and alive. The first couple of days of using caffeine feels amazing but then I feel dead inside again and live like a robot. So in my mind, caffeine is my main target when I try to adjust my routine/behaviours.

It's not, really. Coffee is an anxiety and insomnia machine for me, while nothing made me as calm as amphetamine (even my heart rate was lower).

I do have a professional diagnosis for ADHD.

Hmm, this is an interesting observation. I do have signs of ADHD.
