When you drink an alcoholic beverage, the alcohol is metabolized into acetic acid, which, along with remnant alcohol in your blood stream, is excreted through your pores. If you drink too much, the levels will build up to the point where you develop unpleasant stale alcohol body odor. Excessive consumption will also cause dehydration and can make you snore when you fall asleep. Snoring is usually a mouth-open kind of activity, and when combined with your already dehydrated state, will result in a very dry mouth and some very bad breath.
