Adderall is much more effective than
Concerta IMO. But as much easier to
abuse, party on, stay up on... it's not as harsh as any of the extended release meds using Ritalin. I was on Dexedrine for 2 years, and I was absolutely abusing that. I'd say that's the one to really watch out for... I got 180 10 mg Spansules a month, and found a way to run out usually with 5 to 10 days left.
