I have experienced insomnia about two weeks apart where I’ve had one hour of sleep. I take adderal xr 30mg once a day and it’s out of my system 9-10pm. But both those nights I was not on the medication and other days I fall asleep around 3 on or off the medication. I believe it is because my stress at college my main concern is to know if it is safe to take zzquil on days I take my Adderall. Also I would like to know how often I can take zzquil, as in how many days in a row is too much.
