I take Se----el(not sure about mentioning specific meds here). In the dose I take, it mandates I sleep and has the chemical result of addiction. I don't crave it, but I don't feel better for 2 days, even though I've taken it the next night. When I'm in mania and paranoid, sometimes it isn't enough and I'll stay awake for days anyway, until my crash. Those are hard! Take everything joyous or even ok out of life and experience the worst horrors mentally and depressively. I haven't been in full mania for a while, but when I was being treated for monopolar depression and not bipolar, I didn't sleep more than 4 hours any night. It was cool being able to take 29 credit hours in one semester, but I remember the way I felt deteriorating. After my paranoid month, I finally hit bottom. I made 5 attempts in less that 3 days, pills, choking, chemicals... I'm not given antidepressants any more.
