Normally when I get high on instant release tablet version of Adderall he feels euphoric but, always gets this weird woozy adrenaline rush feeling (almost feels like a downer) where his limbs turn into Jell-O (I don't like that feeling very much). However the other day Swim ran out of instant release pills so, he took 3 or his 20 mg extended release pills and poured the beads into a makeshift mortar and pedestal. Then Swim proceeds to grind the beads into a powder. He continues grinding until some of the powder, when shaken slightly would form into what looked sort of like cocaine rocks that you get in uncut powdered cocaine that hasn't been chopped up all the way. Sort of like the rocks in the picture of cocaine that is on this site, where it says "the international drug community", but not quite as big. Swim then bombed it with a square of toilet paper and almost an hour later felt the full rushing euphoric effects, without any of that weird adrenaline rush feeling that made his limbs turn to Jell-O. What was also exciting about the experience to I was that he felt much more energetic and euphoric than he usually does. I was wondering why this happened? Was it because XR is somehow different from instant release? Or did it have to do with the fact that Swim crushed up the powder so much? Thanks.
