My fiancee has red splotchy skin rash on his face and chest right now. This happened before when he drinks alcohol, either beer or whiskey. And just the other day, he drank vodka and vomitted everything out. He is an alcoholic and was already hospitalized last year from alcohol poisoning. His face back then, from being splotchy red became flaky red during the treatment. I am scared that it is poisoning again, what should i do?
