Makes sense given the mechanism of action.

I describe my adhd as being addicted to nicotine and stopping cold turkey. Except you're not addicted to nicotine, what you're addicted to is a stimulus that is inconsistent and changes constantly. Your cigarette is a constantly changing thing.

Methylphenidate really messed me up, I found Lisdexamfetamine much much more effective.

I still use nicotine, though in vape form these days.
