Trazodone
"My doctor put me on this for insomnia, and I just started taking 50mg of it last night. It is a great sleep aid, the only downside to it is the amount of time it takes to take effect, which is about an hour for me. It helps me sleep all night, and if I do wake up I am able to go back to sleep within 15-20 minutes. A bit of drowsiness in the morning, but not that bad."
