insomnia
"I only slept 20 minutes of REM Sleep, with a slight dream, all night long. No effect what so ever. It was like I didn't take anything. The Belsomra was 20mg, I couldn't believe that it don't work for me, at all.  When I take 30mg of Temazepam , I get about 5 hours of good sleep.  I rate Belsomra 20mg a grade of F.  I rate Temazepam a grade of A.  By the way Ambien gets a F too."
