Most claim that this hangover cure is a (possibly hopeful) superstition, but according to the New Scientist, there is actually some truth to it. Apparently, most beer, wine and spirits contain both ethanol and methanol. The human body metabolizes the ethanol first, then tries the nasty methanol which makes you feel ill. If you drink some more the morning after , the body will start metabolizing the new ethanol again. Of course, you have to deal with the that methanol sometime - this is the hangover cure for procrastinators
