Trazodone
"If I could give it a 0, I would absolutely do so.  Started at 50mg, and felt WIRED.  Wanted to get up and clean the house!  Bumped it to 100mg, less wired, but still wide awake all night.  Bumped to 150, with the same lack of effect.  MD informed me after this dose it becomes less effective for sleep, so why even bother.  15 years of trying different sleep medications and alternatives, and this, I can say for sure, was the LEAST effective I have ever come across.  At it's low price point, feel free to give it a try, and maybe you will be luckier?  Everyone's sleep conditions are different.  But if you get hyper after benadryl, expect the same reaction to this drug."
