Do I have a drinking problem or is this normal behaviour for a student?

I'm a uni student, and I've been going out a lot. My best friends, girls and guys, like to drink a lot, too. I drink maybe 10-15 units of alcohol in a night when I go out (like a bottle of wine, a few beers and a couple of cocktails). Is this normal for a student or should I be worried? I'm a little worried about the health consequences.

By alcohol units I mean a portion or a serving, i.e. one bottle of wine equals to approximately 6 units of alcohol
