False. The 16th century English dramatist John Heywood suggested that the best way to recover from a hangover was to have the 'hair of the dog that bit you'-meaning, another alcoholic drink. The old wives' tale and the expression is a spin-off from the misguided notion that you could recover from a dog bite by plucking a hair from the dog and holding it to the wound. Unfortunately, the advice doesn't work any better for hangovers than it does for dog bites. Drinking your way out of a hangover will only postpone and prolong your misery.
