Trazodone
"I have been taking 150 mg of trazadone to help me sleep for over five years now and it is wonderful.  My only complaint is that I am a little groggy when I wake up.  A couple of years before I started the 150 mg dose, my doc gave me the standard 50mg dose and it did help me at all.  My main complaint was that once I fell asleep, I would wake and not be able to go back to sleep.  Trazadone solves this problem - it doesn't knock me out so I will wake to any noise or to use the bathroom but I am able to fall back asleep with no problem."
