Hi, as a nurse, who`s spent a good bit of nursing career in the drug and alcohol rehab field, I have to agree that it sounds like beeraholic to me too. Lots of people don`t think they are alcoholic because they just drink beer......a six pack a night sounds like a problem to me, and as Gary said, lots of times it`s a sympton of underlying problems. Oral cancer should be a wake up call, but, he may be self medicating to quell his fears.........Hope you can get some help......Dee
