not enough to even worry about right now, though.
Ambien is of course a new sleep aid
and the jury is still out. People have amnesia on
ambien. They go to sleep, but then wake and do silly/stupid stuff. They have no recollection of this after they awaken. One case went so far as to claim a homicide that the defendant had no memory of. That one did not work. A tolerance and dependance will develop with the zanax if used for a great length of time.
