I feel where you are coming from man. If it's anything like the uni i went to, it's safe to say that nightlife at the students union is far more high energy and alcohol fueled than the 'outside world'. And going out sober in that environment is down right fuckin hard! If you can master this, and I'm sure you can, then hats off to you

Glad to see you have your entourage sorted, I think you'll agree that is key in a uni social environment, especially in a single campus where everyone are mutual friends.Sounds like you are doing well at uni game in general, keep it up.

Check out an ebook called 'conquer your campus', I think you'll find it a good read.
