insomnia
"Ambien works great when taken as directed.  IT IS NOT INTENDED FOR LONG TERM, EVERY DAY USE. I have used 3 refills which have lasted me a year, although I was authorized 6 refills in that time..  I am very upfront with my doctor and tell him that occasionally, (due to working Midnight to 8), my sleep gets thrown off, so I take ONE, WHEN NEEDED. If your sleep disorder is to the point that you feel you need it everyday, you and your doctor should probably look at an alternative.  Yes, your body can and will become dependent on it, if for nothing else, to sleep.  It can be an awesome medication, when used properly, occasionally and conservatively."
