insomnia
"After the arduous task of getting pre-authorization for this drug, I paid $60 and it is not helping. I suffer from chronic insomnia and was looking for something to help me sleep more soundly and to wake up restored. Ambien and Trazadone where my go to combo and worked well for me aside from the restorative part. Hence, the move to Belsomra. I started with 10mg  and it did nothing. Then I tried 20mg and it did assist with falling asleep eventually (at least 2 hours), but not staying asleep. I sleep off and on with this stuff and the dreams are pretty consistent, definitely not REM sleep. To anyone thinking of trying this drug, I'd say save your money and keep looking."
