People have wildly different views on alcohol. Most accept it and many like it, but there are some who dislike it and find it very unattractive. Since you said she "doesn't drink", i'm going to assume you mean she doesnt in general rather than her just not choosing to drink this day because of whatever reason.
Sounds like you enjoy partying. Not judging, same here. I couldn't be with a girl who doesn't party and/or has a negative attitude about alcohol. Call me irresponsible but i like getting drunk and I do it roughly once a week. An important part of seeing a girl is being able to kick back and relax with her. Getting drunk with a girl is (or should be) really fun. If she wasn't open to that, i wouldn't be with her for an extended period of time. But..... I mean if you're just trying to get laid here, then that's different.
I'd say it's best not to get sloppy drunk (obviously). I find that your game is killed for the most part when really drunk, expect you always feel like James Bond smooth. Drink lightish beer (not like 8% dark craft brew lmao) and just sip on it. Catch a buzz to have some fun
Just my advice. You're a man, ultimately just do what you like.
