insomnia
"My insurance won't cover the brand name so I'm taking the generic.  I have had awful insomnia lately and I tried other medications that had really weird side effects so I had to stop taking them. With the generic zolpidem I found that it works only if I'm not over tired. I could sleep 9 hours straight but I am still tired, maybe because of personal problems. When it works it's great but when it doesn't then I am up most of the night."
