Doxepin
"I have used all known sleepers and other off label medicines for sleepers and I have taken Silenor 6 mg for 3 nights.  It is amazing.  I fall asleep with no problems and stay asleep for 7-8 hours.  No hang over or other side effects.  I had been taking Remeron 60mg for sleep, as it was the best of all I had tried. I thought the Remeron was doing an okay job until I tried the Silenor.  I am thrilled and feel more rested then I have in years."
