Mirtazapine
"Overall, I would rate 7.5mg of Mirtazapine two hours before bed as an awesome remedy for severe to extreme Insomnia, with little to no side effects.

I had tried all kinds of sleep aids ranging from ambien to benzodiapines, with no effects. I am non to limited responder to Ativan and other benzos.

Mirtazapine works great for me, I get 7-9hrs of sleep, but only when I use the 7.5mg orally disintegrating tablets from Aurobindo. Do not, I repeat, DO NOT use the regular tablets. They had very limited effect on me. 

Mirtazapine will cause some drowsiness if I do not get the full 9 hours of rest, or have to get up early. This is easily mitigated by vitamin b12/C powder. 

Mirtazapine sleep feels natural and refreshing."
