Mirtazapine
"Ive been in recovery from opiods for 14 months( which my dr prescribed for chronic hip bursitis. worse thing ever), anyways,I take 15mg of remeron and sleep like a rock. I take it 1 hr before bed, and I don't wake up once in the night. I used to toss and turn from pain every 1hour and woke up exhausted.  Now I sleep straight through and my anxiety is gone.  I never considered myself a depressed person, but I can say my mood is even better.  If you cant sleep, I would def recommend this!"
