I am prescribed 70mg vyvanse and I have been out for a month, just got more Tuesday. Took it yesterday and couldn't sleep. I took 30mg ZzzQuil(usually knocks me out within an hour and a half) and fell asleep about 2 hours after taking it, then woke up an hour later and was unable to fall asleep again. Is there anything I can do to help me sleep until my body gets used to it again? I'm only 17 so trying to get prescription and OTC sleep pills are kinda out of the picture.
