Mirtazapine
"15mg was too stimulating (actually made me feel jittery) but 7.5 did help me fall asleep faster and sleep longer.  Stopped working at all after a few months so I'm tapering off.  I did not experience any increase in appetite, though I did gain a few pounds (which I was able to lose while on the Mirt.).  Side effects were tolerable:  dry mouth, slight headache.  I confess that I'm jealous that so many people find this med super sedating - it just didn't work that way for me!"
