insomnia
"I've been taking zolpidem now for a year, always get a good night's sleep. Those of you who take the Controlled Release have problems because that's the one with slow release, not good, I also break pills in half or quarters, something you can't do with slow release CR either. CR makes you wake during the night and causes all sorts of problems, sleepwalking, etc. Take instant release zolpidem, see the difference."
