CARTHAGE, TX — Most people get a little tipsy after a few drinks, but what about someone getting drunk without taking a sip? It’s a true story of a man some would call a walking brewery. The Texas man suffered symptoms of being drunk for nearly five years. A team of researchers discovered a yeast infection was causing fermentation in his intestines. If he ate high sugar or high carb foods, it added to the feeling of intoxication and actually raised his BAC level. His doctors gave him an anti-yeast medication, and the problem cleared right up.
