I'm the same way really. In my first year at uni, I simply enjoyed getting ratted most nights. In the second year, I still went out a lot but drank noticeably less. And now, in my third year (although I've only been back a week or so for over freshers week) I really don't have the desire (or ability, I fear

) to get pished all the time. Don't get me wrong, I still love a couple of pints, but I prefer to keep it to that, and down the pub rather than getting shitfaced in a club.
Though tbf it's always been like that, the pub bit at least. I guess my freshers year was ust the novelty and so on.
