Well, I'll join the official "I've flushed my MDPV and am never touching it again" club.
Considered joining a few days ago. Luckily, I'm a black-belt in self-deception.
Still, I'm nearing the end of a 250mg bag and haven't fucked myself over too badly. (Yet.) Granted, the compulsion to re-dose is very, very real, and I've given in to it plenty of times. Flip-side, it's never burned me with anything worse than sleep deprivation and jitteriness. Sometimes it'll jack up various pre-existing (and extremely minor) anxieties/paranoias/phobias a bit, but never to the extent that they're actually fully
real (they tend to stay surrounded, in other words, by that layer of common sense that just keeps saying "This isn't actually happening.").
The most annoying side-effect, actually, is what seems like some sort of very low-level formication (the classic bugs-under-the-skin thing), probably at least partially psychosomatic, combined with a long-standing hyper-awareness and slight fear of various insects and things in my flat. When your ears stay half-trained for these bastards 24/7 anyway, the tiny shots of adrenaline and reflex scratches every few minutes can get to be a real bitch.
EDIT: Forgot to ask, has anyone experienced any particularly rough 'physical' side-effects? I sometimes get a light strain-type pain in the calf of my right leg, but am not entirely sure whether that's down to the drug or just coincidence. Also, tend to get 'pins and needles' type feelings a lot more often (e.g. lying down reading, with the book held up above me, the blood seems to drain from my arms very quickly). Something to do with dilation of blood vessels, presumably -- in case it isn't obvious, I know next to nothing about biology.
