Ambien (zolpidem) is a benzodiazepine analog (z-drug), it works on the same GABA neurotransmitters as benzos. It is well know to be highly addictive as it is also well know to cause major rebound insomnia when stopped.
Not worth it in my opinion, you won't die from not sleeping, you might feel crappy for a while but eventually you will sleep. Taking a z-drug only puts off the inevitable, plus whilst it might "put you out" it stops slow wave and REM sleep, so you actually don't get the sleep you need, makes no sense ........
Type "burt reynolds ambien" into google to get some stories about its effects on some people.
