Officers look for other signs of intoxication besides breathalizers. The look at you ability to do certain physical activities, the responsivness of your eyes, you ability the speak coherently, etc. Ambien will cause drowsiness, and dull the senses somewhat, and if you are not used to taking it, an officer can tell. So yes, you could be DUI on Ambien.
