I've never had Adderal, only Dexedrine and Ritalin.
Dexedrine is pure, clean, gentle on the head but seems to carry a light body load mainly focused on stayng hydrated. If I didn't pound water my kidneys hurt.
Ritalin is poison. Taking the smallest does, 5 mg, had me splotchy red and rapid cycling like I was bipolar, accompanied by mildly impaired cognition. Apparently that's how it affects most adults who didn't take it as a kid. The way it affects most kids is to turn them into zombies. Disgusting substance.
