On a serious note, I have a feeling that this another of those things that only really exists on TSR.
Sure, there's a lot of booze at university - but why wouldn't there be? Get thousands of 18-21 year olds together with a bit of liberty and money, and what do you think will happen?
But I don't recognise the idea that there is no socialising at university that isn't centred on consuming. That's not a reality. If you don't drink, you don't drink. No-one will care, but you will have to either put up with people who do - or find like minded people.
