I can get overstimulated now ._. I don't know if it's just a me thing, but my partner took me out to the shops while my medication was in effect and I reached a point where the colours and varieties suddenly was too much, and we had to step out while I tried to recover. It was a totally new experience since I guess normal ADHD brain discards irrelevant (and sometimes relevant) information quickly like nobody's business, but medicated brain doesn't do that as much.

Staying awake when I'm bored. I was working in companies with long ass meetings for 3 years before I got diagnosed and I've been falling asleep in classes for even longer. I've slapped myself, pinched, drank water, washed my face, and all it took was medication for that uncontrollable exhaustion to...disappear. No more shame for something that I've been completely unable to help. It's a massive change.
