… ADHD? Which I think is just being Highly Sensitive and having impaired sleep?

I didn’t know that sub-optimal levels of arousal could make you tired/sleepy/ or even fall asleep.

I used to hate driving because I’d have to pull over, get out and do jumping jacks to stay alert sometimes. Then I came across something (to link if I find it again) that suggested it might be ADHD. I got diagnosed and now it’s the number one reason I take amphetamine medication – no more getting tired while driving! Caffeine never worked for me as far as alertness.

Turns out driving was SUPER BORING for me. The only thing as bad or worse was trying to read Huckleberry Finn – I kept passing out every time I tried in high school.

If I engaged my brain with interesting stuff, then I wasn’t paying enough attention to driving and could only go somewhere I could get to on autopilot. Short drives were ok, but longer ones not so much.
