I'd tried it before, but it'd never done shit. Did 472mg (2 bottles of Vicks 44) and I'm definitely feeling it right now. It's pretty crazy. A week or two ago, some guy started a thread saying he worked out on this shit. I have no idea how I could get to the gym, much less have a productive work out on it. But he's right about the painkilling/disassociative effects. You can still feel yourself, but its almost like you cant.
