ambien is just fucking WEIRD stuff.
Makes people sleepwalk, sleep-all kinds of other things best not done whilst non compos mentis, makes users trip in a weird dissociated kind of way, temporarily rouses coma patients in vegetative states previously.
I've been prescribed it for sleep a couple of times, as well as the other two 'z-drugs', zolpidem (imovane) and that other fucker, I forget the name of it now, but it was totally useless..err..zaleplon, thats the one.
Both ambien/zolpidem, and zopiclone made me have some weird experiences, full on trip out with the ambien with almost no memory of it afterwards, and with zolpidem, weird ass noises, pinging, ringing sounds, noises like one would see in a cartoon if a giant spring suddenly uncoiled, all out of the blue. Zaleplon was just totally useless
