insomnia
"I've been taking Ambien for about 8 years now due to chronic insomnia.  Multiple medical issues have caused most of the problem with not sleeping.  I already have 3 fusions in my neck (one of which is falling apart and causing a compressed spinal cord that my NS is trying to avoid further surgery on so that I don't have to have rods in addition to the screws and plates that are already in there) plus I have laminectomy from L2 to S1 with bulging discs, fibromyalgia, bone on bone arthritis in both knees and I also need both hips replaced.  Oh, there are also a couple of bulging discs and bone spurs in my cervical spine in addition to the problems already mentioned.  I have never had any side effects or trouble with the Ambien at all."
