Trazodone
"I have been taking trazodone for over 7 years. Was prescribed for insomnia and as long as I take it, it's fantastic. Sleep like a baby. Takes about an hour for it to work and will cause nausea on an empty stomach. If I don't go to bed within an hour of taking this medicine, I will be staggering around running into walls, furniture, etc.  Tried many different sleep meds and this one was the only one that worked for me. I believe it has also provided benefits with treatment for depression and anxiety, although never formally diagnosed."
