ve been prescribed 90mg of Adderall a day, Concerta 54mg (2 in AM and 2 after lunch), now
Ritalin SR 20mg and take 2 tablets 3 times a day. And, I am addicted. I take 400 to 500mg of Ritalin a day and start having anxiety and panic attacks days before I run out, because I know how difficult the withdrawals are from not taking it. I've been to an addiction rehab center for it and spent 30 days there.
