Hi my husband has been experiencing problems after consuming alcohol, he had two drinks last night, vomited three times and has diarrhea , whats wrong?

Previous problems?: with alcohol consumption? Two drinks is a small amount to be causing symptoms the next day, if it hasn't previously caused problems. Also, diarrhea is pretty unusual. Sounds like he possibly has something else going on, like a virus or food poisoning. Try just clear liquids as tolerated, consider getting a Concierge consult or seeing your GP or Walk In if not better after a few hours.
