Alcohol is also bad for your muscles. Muscles needs fuel. That fuel (= sugar) is provided by your liver. But after you drunk alcohol your liver needs that fuel itself. Becouse alcohol slows your bodyfunctions down the liver itself needs more fuel to keep up. Less to none fuel will go to the muscles. They get weaker. Making your motions even less controlable. That's why you feel stiff and tired after using (to much) alcohol.
