insomnia
"Ambien has been a huge help to me. I have horrible hot flashes whenever I try to fall asleep and end up awake all night. When I take half an Ambien I am able to fall asleep and I do not feel tired or out of it the next day. I am so grateful for this medication. It's helped the quality of my life substantially. I've never experienced the side effects others mention, I simply fall asleep."
