I tried this stuff a little while ago. I know I shouldn't have... but that's the only way I would know what it tasted like... I only had a small amount of powder, and it tasted horrible, similar to magnesium sulfate.
The warning not to do this makes sense, after a while my jaw went numb, it was kind of locked, a strange sensation. I'm sharing it just for the sake of knowledge, rest assured that it was just a few powders, and I'll be fine.
It must be really hard to drink the necessary amount, and I think it's impossible not to vomit.
I'm rethinking throwing the stuff away.
The taste is horrible, seriously. I'm sick of half a dozen crumbs...
