insomnia
"I have found Mirtazapine to be a very safe drug with almost no side effects!
I not not only had depression, but couldn't eat or sleep.  My psychiatrist is
excellent.  It has been a delicate issue because I was still on 25 nortriptyline.
Finally, I've been on both for a few weeks.  I do hope that my doctor will
eventually have me only on Mertazapine & no nortriptyline."
