One of the most fundamental effects of consuming alcohol is dehydration, as the alcohol literally sucks the liquid from your body, leaving you with headaches, nausea and other unpleasant side effects. Our bodies are composed of roughly 70% water, and when alcohol depletes those levels to compensate for the effects is has on the body, the effects are incredibly obvious. If you are suffering from alcoholism, one of the best ways to eliminate the terrible symptoms is to flush your body with water as often as possible. This will prevent the more serious side effects that so many alcoholics experience.
