We usually use a Present Simple, like “How often do you consume alcohol?” Thank you. olga55 Joined on Wed, Jun 18 2008 Full Member 150 Tenses, Present Tenses, Present Perfect, Present Simple, Sentences

	Grammar Geek  +  652607 Fri, 23 Jan 09 02:09 PM I agree with you, olga. I would expect "How often do you consume alcohol?" as the question as well. Perhaps something had changed - the person is in the hospital, and clearly is not drinking right now, so the doctor is asking about past habits up until the time of his admission?
