Yeah if you don't remember what happened the night before, having taken ambien, you probably had a grand time. Oh man, did it ever help me sleep though. Sleep on Ambien is *amazing*. I rarely ever sleep well or regularly and wake up feeling rested, and nothing else works like ambien does that I've been able to try. The fun is really secondary to the experience of getting real rest. It's nothing like over the counter crap that makes you dizzy and woozy but not at all sleepy.
I've never taken powerful pain killers besides codeine and codeine sucked enough ass. I can't even imagine what drives people to get addicted to it or to try to get high off it; lack of real drugs to get high off of I guess. :/
