Trazodone
"One of my favorite medicines of all time. I have taken this for depression/bipolar disorder, insomnia, and currently fibromyalgia. It is the only anti-depressant I have found that I can take and not start swinging toward the manic side. I actually feel more refreshed and get a good night's sleep after I take it. I will note that I do not normally take it for long periods of time- only when I need it (this may be days, weeks, or months). There is no withdrawal and you do not have to dose up or down with safety concerns."
