Hahahahah, my friends used to buy addy off me and pop like 150 mg and play WOW for 3 days straight.  You are gonna be fine, you just won't sleep for a few days and will be super jittery.  there is no way to flush adderall out of you system quicker.  did you take XR or just the tablets?  Honestly just smoke a couple of bowls and have a super productive high.
