i was on adderall for awhile too.......man, what a drug!!  some pretty weird thoughts creep into your mind after being awake for 100 hours with no food.  they didn't take me off it, slowly or otherwise.  i quit.  because what i described above is about as far from the norm as it gets.  withdrawing from amphetamines is no picnic my friend, i feel ya.  you made it through that.  energy drinks, sugar and crappy food should be a snap.  all up to you.  you want to sleep, quit ingesting crap!  easier said than done, but there ya have it
