Hi, I'm 15 I take ADD medication to help me concentrate in school, it is prescribed. Usually I only take it on weekdays because I don't need it on weekends. Since it is Spring Break I have been off of it, today I had hockey. I'm a goalie and it helps me concentrate. I took it this morning but later than usually around 11am- noon. and now it is 3am and i can not sleep, is there anything I can do or take to help me sleep?
