one night i think i took bwtween 6-10 20 mg adderall pills( i had a tolerance by this time, use to be an amphetamine whore), becuase i was cramming for a huge exam... well i at one point started getting dizzy and hyperventalating... then i started the shakes and i was really cold but hot, my joints ached and i felt like complete shit, i started to not be able to see and started pukeing bile from the stomach, because i hadnt eaten for a couple days. My lips were cold but my whole body was burning hot, then i realised i overdosed and i was really scared so i got a huge thing of water, saltines, my vitamins and some peanut butter.. I sat in my room awake all night eating and drink water (sipping of course) i was so scared to fall asleep and have a stroke or something, since then i havent really done any stimulants- it was just a scary moment and i dont want to put myself in danger like that again.. Id say oding on a stimulant... IMO
