insomnia
"I have been using zolpidem(5mg) over 3 years now. It's suppose to be only 2 weeks use but after I stopped using 2 weeks I couldn't fall a sleep all night. Since then I'm using everyday. I'm afraid if I stop using it I can't fall a sleep again. I'm glad I'm using only 5mg.  It's great for initiating to sleep as it advertises."
