Mick, I think I read this in the Berkeley Barb, a Vietnam Era underground newspaper: it's the hippy's cure for the flu: Toke up, crawl into a sleeping bag with your girlfriend, make love, go to sleep; when you wake up, start the whole process over and over and over. In three days your flu will be gone (of course it's usually gone in three days, anyway, but you don't usually enjoy it). I suppose the original also said something about replenishing body fluids as needed, and I don't recommend peeing in your sleeping bag, not if you're going to stay in it for three days...
