"i suffer from major depression, generalized anxiety disorder, and severe insomnia. i&#039;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&#039;s generally my bladder that wakes me.  i don&#039;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)."
