one of my college roommates who mixed too much wine and beer
Yuck, but I think the key part here is not "wine and beer" or even "too much," but "college."
I make no claims to be a real lady, so I drink wine, beer, martinis, margaritas ... just about anything in front of me. Separately, together, whatever. But I try to be a bit measured about it. More so than in college, anyway.
