I never found zolpidem (Ambien) recreational. I actually hate the feeling while on it. I get this weird feeling like everything around me, even inanimate objects, are alive. I hallucinate stupid things, like for example one time looking very closely at my fingertips I could see little "hairs" which looked more like spider legs or something (I am totally aware that I am hallucinating too). I don't even feel sedated, in fact, I feel somewhat more active (not stimulated, but just active). I've never blacked out or anything on zolpidem and I've taken doses up to 50-60 mg. I've had some shitty experiences with zolpidem, to say the least. Overall it's just an uncomfortable feeling that I do not enjoy at all.
