as a counterpoint if we’re doing anecdotes:

i had adhd diagnosed as a kid, medicated for a while, then stopped. didnt do great in school, just ok. struggled at uni with timekeeping and grades. made it decently, and then had some decent jobs.

got quite lucky, but always had issues with social skills and being too talkative. eventually got a tough job that needed a lot of personal initative and went back on meds. vyvanse has changed my life, allowed me to focus on my thoughts, keep organised, and not only helped me excel, but also fix my sleep schedule, get promoted, and just generally live like a normal person.
