I am a hard worker and have made a good amount of money so far in my life, but recently my college math classes have been kicking my ass, so i tried Adderall XR and Vyvanse.... I read Fabric of The Cosmos in one day, I am a machine on this stuff. I cannot, however get a prescription (apparently my good GPA and academic standing made them think i was full of sh*t). Where can you get this stuff? (the kind thats not made from Rat Posion. Thanks guys, peace out.
