I too keep staying awake until sometime in the middle of the night. I was still up at 4:30 one morning and I have to get up at 6 to get to work. Last night I saw "The X-files" and a "Law & Order" both of which I love but 6 am can come really early. Then when I am having a bad episode I sleep all day. No wonder I am screwed up! When I first got on meds and was going all night without sleep (and still working - that was fun) I took Trazadone too. It helped me. I am not on anything for sleep now.
Hope you find what works for you!
