Ambien is supposed to be used as a short term solution 7-10 days. My doctor had me take it for insomnia for 6 months. I became addicted and had to go through a withdrawal period. It is devastating as it induces episodes of anxiety, nervousness, diminished short term memory and reduced abilities to concentrate. It also suppresses the dream state of sleep, so while you get some rest benefit, normal sleep is disrupted when you stop using. I would advise against long term use!
