I used to get those for sleep difficulties and they were very interesting, to say the least. My experience was that if you could push through the first half hour or so, they probably wouldn't put you out, per se. Oh you'd be whacked but you've gone past the point of them doing their intended job - to get you to sleep. My biggest problem with them, aside from coming to and realizing you've been doing stuff and what not and have no clue whatsoever what you've been up to the last 5-30 minutes. BTW, I'd always take them after the rest of my household had gone to bed, so I could be a little whacky and not raise any eyebrows as to what's wrong with me. The real problem was that out of the blue, like when I'd be standing at the john taking a leak (or standing up eating something in the kitchen) and I'd just pass out, for lack of better words, and I wouldn't realize it until I was more than 50% on the way to the ground. Not much one can do at that point but maybe turn a little or stick your arm out but you "are" going down! I used to break shit, and me, all the time. Used to piss my wife off to no end! I finally said, enough is enough, I'm not using these things like I should and eventually I'm really really going to hurt myself (more than the bruises etc. I used to get), so let's just quit these things while I'm ahead. As much as they were a quite different and interesting drug than probably anything else I've ever taken, they just weren't worth it in the end. So, good riddance. It was fun, sort of, while it lasted but clearly I was not meant to take these things and I'd be a fool to continue (and to what end anyway?). Please be safe OP, as others have mentioned, and enjoy as much as is possible
