To expand on this: for about two-three weeks after starting to take a Ritalin variant (this was in working life, I didn't have meds in HS + college for reasons) I was pretty on edge, getting pretty mad at stuff and even just pre-emptively cancelling meetings with some friends because I felt I would start yelling at the next person who talked to me.

I've heard this happen to other people too, and it's frustrating, but luckily it also comes with the feeling of clarity that was always missing, and fortunately people around me are supportive. No lasting damage, just "oh yeah I was a bit on edge then"

Oh, that. I had something similar during the period when a dose was wearing off. So every 4 hours or so.

My dr prescribed Paxil, which did away with that problem.
