"my insurance won&#039;t cover the brand name so i&#039;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&#039;m not over tired. i could sleep 9 hours straight but i am still tired, maybe because of personal problems. when it works it&#039;s great but when it doesn&#039;t then i am up most of the night."
