Hey Im a guy about 140-150 lbs and took a 15 mg pill of adderal and I took it at 4 pm and its 3:30 am. It's my first time when will this stuff where off so I can sleep?
Generally speaking adderall will keep me awake for 12 hours. Even at doses as low as 15mg my general rule is I wont be sleeping until 12 hours later. The above poster is correct when he says it is a low dose but the residual stimulation will probably leave you tired but unable to relax enough to fall asleep. I would avoid doing adderall before 2PM in the future if you want to be able to fall asleep at a normal time.
