I used it and it did nothing for me.I came into the world with abnormal sleep habits.I'll get raked for this one but ambein is what i use and it works for me. I can quit taking them and my sleep habaits will return almost in a week.which is sleeping all day and staying up all night.Without the ambien I cannot function in a normal society.I give them to my wife an she gives me one a night keeps the rest in a small safe that I dont know the combo to.
