"I honestly have real trouble conversing with people who consume it on a regular basis and/or ever get drunk."
Honestly, you're really going to struggle with life. Forget university, what about when you get a job afterwards? All your coworkers will drink and will frequently talk about going to the pub after work, or having wine with dinner, or what crazy things they did while drunk at uni (or last weekend).
Maybe consider moving to an Islamic country like Saudi Arabia, where alcohol is outlawed? That's not a joke, it's a serious suggestion, because I don't think you're going to be able to handle life in the UK.
And before you accuse me of being biased, I don't drink. My father was an alcoholic and was violent towards me, my mother and my siblings while drunk, so believe me, I hate alcohol probably even more than you do. I just understand that it's part of life in the UK and you can't avoid it. My boyfriend drinks, and I deal with it. I just ask him not to drink red wine around me, because that was my dad's drink.
I deal with it. You can too, or you can just move to a country where you won't have to.
