Ambien is a wonderful sleep aid. I have perpetual insomnia and was not helped by other sleep aids. Ambien really worked for me.

However, one of the side effects is that it can cause sleep walking and doing things you don't realize you are doing and have no memory of later on. For instance, After taking Ambien and going to sleep I apparently got up, got on my computer and purchased many things on e-bay and other sites. Some of the things I purchased I had no need or desire for.
