Insomnia
"Brand name Lunesta works like a charm. I get 8-10 hours of sleep a night. I have never built up a tolerance and I have never had episodes where I did not remember things if I didn&#039;t go to bed right away. I have fibromyalgia and REM sleep is very important. Last month I got the generic brand and I haven&#039;t had a good nights sleep since. I can&#039;t fall asleep at all. If I start to drift off my brain suddenly wakes up. I&#039;m not even getting 2 hours of sleep a night and that is after laying there till it&#039;s almost time to get up and I take 2 muscle relaxers to get a little sleep. Now my pain is unbearable."
