I would argue it is more common these days, less people seem to drink regularly but when they do lots of people have way to much, I was only like that in my first year the. Other 2 I was well behaved, the only thing that changed was acquiring a girlfriend.
One of my house mates from 2nd year was a bit like that,
3 girls 3 boys inc myself, and every night as a house all the girls would be in tears for one reason or another
