Dear Amber90, I am sorry to hear about your case, and I am not sure if my experience would help.
I have had Adderall for several years. My recommended dosage was close to the limit. But sometimes (weekends), I would skip having it, and on busy weekdays, have an extra pill. However the only side effects that I’ve ever felt were loss of sleep and reduced appetite.
I used Ritalin in the past, and switched back to it. The effects of both drugs (Ritalin/Adderall) are nearly identical; however Ritalin is somewhat more effective.
