Oh dude...this always happens to me. First, you need a box of razor blades. New ones will do, but older rusty ones, while harder to find, are optimal. Ok, once you get a hold of some razors, radomly make 2" long slices all over your body, it's best if you do at least 50. Now, grab some salt, and coat yoursefl with it completely. You can simply pour it over yourself, or you can get a little fancy and fill a plastic swimming pool with some and roll around in it until throroughly coated.
Let that sit for about 8 hours, then finish up with a alcohol bath.
Works like a charm...
