Alcohol is a very harsh chemical - it actually contains poisons, which is why alcoholics eventually die of liver failure after it builds up in their body for long enough! People who drink a lot almost always have irritated throats (pharynx and esophagus), stomachs, and intestines. They suffer from ulcers and chronic heartburn. The only way to really treat this is to drink in moderation - one normal-sized drink every day or so does not hurt you, and gives your body time to get rid of the poisons before you drink more.
