I can't lie, I thought there would be less drinking at York, but there drink culture here is pretty big. I do feel left out sometimes for not drinking. I saw something the other day saying York was #5 for drinking in the UK but I don't know how true that is. Unfortunately, it is a big thing everywhere, even with societies, but there are some that don't drink or prefer to do non drinking things. Some societies occasionally do non-drinking events. You'll probably have the same issue at all unis tbf. I don't regret being someone who doesn't drink much (can't afford it either) but it can be isolating at times. I'm not a non-drinker, but I don't do it often at all, whereas most people in my flat go out at least 3 times a week (Wed, Fri, Sun).
