That's interesting - are you sure that's pyrazolam?? Because my experience was quite the opposite, that it was a very "transparent", non-sedating benzo - and that's generally more in line with what I've seen reported by other people elsewhere.
The same thing has happened to me recently, for some reason... Recently I've been taking just 3g doses at a time and surprisingly seem to be getting something out of them...
A few days ago I dosed 5g, then felt it wearing off like 3 hours later, and dosed another 6g... that made me pretty nauseous, and actually I ended up having to do some stuff the rest of that day so didn't redose - but I was still feeling it probably 12 hours later. That made me think perhaps I was doing kratom a bit wrong - expecting it to have really pronounced effects such that the experience of doing anything at all was opiatedly nice, but obviously, I guess, these effects are going to be short lasting... the last few days I've been dosing a lot less and - perhaps unsurprisingly - I'm getting a lot less of the negatives, a lot less of an obvious crash, frustration with the short effects, and increased magnitude of uncomfortable effects... I think there is something to be said for the idea that with increased usage you can appreciate the effects more, and get something from a lower dose, rather than just sledgehammering it to get a definite but less sustainable buzz... hopefully that's it anyway, and not just a light opiate withdrawal creating the illusion that small doses seem to do more.
OT today: 4g kratom in 3g+1g, 40mg RGPU-95, coffee.
