Hi Oceanlover,
I believe that your family doctor will be bound by confidentiality rules which would prohibit him/her from telling anyone (even your family) about your alcohol intake. I understand that if you aren't ready to quit that telling may put you on the spot later. But I'd add to those who say that this is a medical safety issue and that your health should be your primary concern here.
I felt much better after I talked with my family doctor, although I avoided it for a long time for similar reasons. It was a relief!
