Hi. Thank you. I have a very close friend who I believe has trouble with alchohol. He does not agree. In recent months he has fallen several different times when drunk. He fortunately was not badly hurt. This week he has vomited profusely on two different days. Once he was sitting in his chair and could not make it to the bathroom it was so sudden. He is almost always drinking when he is awake. Could the vomiting be caused by the drinking. He drinks hard liquor mostly with some beer and wine and has for many years but worse since retirement 3 years ago.
