I don't get that much sleep maybe 4 hours max because of school. It takes me 20 minutes to get up because I'm so tired. It doesn't take other people as long to wake up. In the weekend I'm not allowed to sleep until 2 AM for studying and I have to wake up at 9AM for tutoring. 7 hours is enough for a person but I don't feel refreshed until I sleep for 12 hours at least. Can anyone tell me what medication I can get to stop being so tired? Also I can't exercise that much because I don't really have time.
