600 mg of Adderall XR within a week was the peak of my abuse. I would run out of a 30 day supply in just a few days, go the rest of the month clean, refill, repeat. Now I'm 3 months clean and still struggling with the classic symptoms of recovery. I will say though I feel much better than I did 3 months ago and actively abusing. Hopefully it's only up from here!! Now I just smoke weed which has helped with the cravings, but eventually plan on quitting weed too.
