Ambien is really tricky shit. Sometimes it works for sleep, sometimes it doesn't, sometimes it makes you hallucinate. I took ambien one night, and apparently decided to do a cigarette run in the car(gas station was only three blocks away, mind you), and ended up being arrested and charged with DUI. All they found in my system was carisopridol metabolites, but that was enough that I still had to plea bargain it to a lesser charge. IMO Ambien sucks ass, I'd find a better drug to get high on, and no doubt.
