Mirtazapine
"Mirtazapine is a miracle, but you have to take a SMALL dose, meaning about 7.5 mg to 15 mg, no more than that.  Larger doses cause too much adrenaline release, so if you gave up on Mirt before, try it again with a pill splitter at a very small dose, just before bedtime.

It will help you sleep, and it has virtually the opposite side effects of SSRIs, meaning no sexual side effects, and no anxiety increase (only decrease).  I take it for debilitating anxiety just as I described."
