My boyfriend drinks and I very rarely do, same thing with smoking but to each it’s own right? The thing is my boyfriend bought an 18 pack of beer (cans) one day last week and was done with half the pack that night and finished the rest off the next day. He doesn’t get drunk to where it’s a problem and he handles his liquor well I guess but should i be concerned? I mean two beers is no problem, but nine back to back within the same night worries me. It’s getting to a point where I joke he’s an alcoholic but I’m worried. He drinks alcohol like it’s water. Advice?
