By textbook definition, you are an alcoholic. But I don't agree with a lot of textbooks. I think you're having a good time and enjoying life. No need to defend it unless it becomes a problem. If you wake up and can't move until you have a beer, or get physically ill if you aren't drinking, then yeah, find some help. If not, enjoy life. I drank heavily almost every day from 18 to 30, then just quit with no problem. People in my life during that phase swore I was a raging alcoholic. Fuck everyone else, it's what matters to you.
P.S. I bet your Korean girlfriend is super hot. I'm half Korean and Korean women are fucking gorgeous! And they cook, clean, and spoil their men.
P.P.S. Did you know over 80% of Koreans (Asians, too) are allergic to alcohol? I bet your girlfriend turns beet red when she drinks. Most Asians do. It's because we're allergic to it, but still enjoy the hell out of it!
