insomnia
"You can do things and not remember them. You will tell awful stories about squirrels jumping out of glass boxes, and say things to your spouse/significant other you don't mean if you try to TALK while on this drug. So by all means do not take until the very last thing before sleep, i.e. you are in bed, ready for sleep. It kicks in super fast and you won't know what hit you. You only get 5 to 6 hours of sleep on Ambien but you feel rested with no druggie zombie after feeling. Note to single parents taking this drug: you will be worthless in an emergency situation and helpless to assist your children in a fire, a break-in, a trip to the ER at 1 a.m. (never drive on this drug!!!)"
