insomnia
"Ambien is a lifesaver. No matter how tired I am, I can't fall asleep or stay asleep. With Ambien I sleep all night. I have been taking it for about 3 years but I ONLY take 5mg. I think the mistake people make is they take too much. It's not supposed to drug you and make you pass out. It allows you to fall asleep naturally. No need to increase amount.  Try it"
