This was recently a segment on 60 minutes where a man became so alcoholic from eating high carb & sugary foods that he would fail a sobriety test. He got into car accidents & lost his licence for drunk driving. When he changed his diet, the alcoholic problem went away.

"What most people don't know is that yeast also produces alcohol in the body—enough to make some people feel drunk and give a positive reading on a breathalyzer test. Most people with yeast overgrowth can't touch alcohol because it makes them feel so rotten. " http://www.needs.com/product/NDNL-0704-01/a_Candida
