I am a 25 year old caucasian female, married with an 8 month old child. After having an ongoing sinus infection for more than a month, I have developed a sudden alcohol intolerebce. Just one drink will give me severe nausea, vomiting and loose stools. I now have sulfur tasting burps, increased gas and continuing nausea. Food does sound appealing at all. What could be causing this? I have been diagnosed with IBS in the past, but this is totally different.
