depression
"Remeron at low doses worked beautifully for my insomnia.  At high doses (I was on 90mg. at one point for depression), it was useless for me.  As my doctor once put it, "For depression, Remeron is not a heavy lifter."  But for insomnia, it was a God send.  The only problem came when I tried to wean myself off of it.  I had little trouble until I got down to a quarter pill (0.375mg).  I got terrible rebound insomnia and eventually had to go back on.  It also made me gain 14 pounds."
