I used to have really insane insomnia to the point where I literally had to exaughst myself in order to sleep. I would pretty much skip and entire night of sleep, go to work for 10 to 12 hours (very physical job), come home thinking I would pass out since I slept 0 the night before but end up being awake again and only getting like 4 hours of sleep if that in a two day time period.
Seroquel pretty much forced sleep on me but I had to make sure I took it early enough that I didn't wake up to the alarm feeling groggy and out of it. I recently stopped taking Seroquel because the weight gain was really pissing me off and when I switched from day shift to the graveyard shift and cut down on caffiene I found myself doing nothing but sleeping and feeling tired all of the time. I also stopped taking my Lexapro.
So instead of not being able to sleep I have gone to other extreme of sleeping too much....

can't win, can we?
