Mirtazapine
"Loved this medication.  Particularly loved the sedative side effect, because I had been unable to sleep more than an hour or two at a time, prior to taking mirtazapine.  The only drawback was that my appetite, and consequently my weight increased dramatically over time.  After taking it for 10 years I had to find a medication that would not make it so difficult to lose and maintain weight, but I have never found a medication that made me feel so good, relaxed, and able to sleep."
