"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&#039;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."
