insomnia
"I have been taking Ambien on and off for 8 years for severe insomnia, mostly related to anxiety and post traumatic stress disorder. Over time my body has built up a dependence and a tolerance. I will lay awake till 5 am if I don't take it miserable and exhausted for days. The generic doesn't seen to work as well and since I have been on it so long I usually have to take 20mg to get a full nights sleep, but with certain generics I still wake up at 3am and can't go back to bed. It has been a God send over the years as I tried everything else. I was treated for depression but those medications made it harder to sleep. At some point I would like to stop being dependent on the medicine but every time I try to quit I go through weeks of with no sleep."
