No, def not Slavic. I'm from South Africa - a drink after work, either at the pub, or at home, is very much the norm. And weekends the sky's the limit. (OK, now that makes it sound really bad..lol!)

But yeah, drinking on psych meds is not a good idea. Most package inserts warn against it.
Drink a non-alcoholic cocktail, or any other drink with your friends when you go out to sort of fit in. I know it's not easy.
