insomnia
"I suffer from major depression, generalized anxiety disorder, and severe insomnia. I've been taking 15 mg of this plus 100 mg of Trazadone each night, to sleep, for almost 2 years. (on top of my depression meds, which we are still playing with).  The mirtazapine has been a life saver.  The trazadone helps, but without this drug I only slept an hour or two at a time.  with this, I generally sleep 6 hours before I wake up at all... and even then it's generally my bladder that wakes me.  I don't get any of the side effects people here keep talking about (drunk feeling, inability to wake up, numbness in the mouth, excessive sleep, etc)."
