If you're having doubts if you can stay up long enough to fix your sleeping pattern, here is some advice to stay awake. Smoke 2 packs of cigs until you're sick, suck on some
Bawls, find an addictive video game, smoke another pack of cigs, vomit, run out into the streets and do laps around the block, get back home and eat nothing, but drink 3 pots of coffee consecutively, collapse onto the bed, stand up and slap yourself in the face repeatedly when you realize you're giving in.
