Just about every drinker has woken up with a painful headache, dry mouth, nausea, and dizziness that come from overindulging in too much alcohol. The definition for the word hangover is the unpleasant physical effects following a heavy use of alcohol. In other words, a hangover is the painful day after drinking one drink after another. There is no cure for a hangover, just ways to prevent it from happening.
Hangover is where the active ingredient in alcohol, ethanol, is transformed to pyruvate causing the toxic chemical called acetaldehyde (Kater, pars. 4-5). Acetaldehyde is a chemical that is processed by the liver at a fixed rate no matter how much is all ready in the blood system; this process uses a lot of the body’s energy; therefore, the body tries to restore the normal energy causing dehydration (Kater, par. 5). Dehydration is what causes all the horrible feelings the drinker comes across the morning after drinking.
