Do you mean Ambien? My Dr. prescribed it for me a couple of months ago because between the night sweats, depression and dealing with an elderly mother that lives 1500 miles away I was waking up every 20 minutes. It is not meant to be taken every night, I was told to take it only when I really need it. It seems to work and I didn't experience any sort of drowsiness the next day. I've only had to take it twice.
