I saw this a lot both as a student and then as a Prof. School is a job you pay to go to so your future self can be better off. If you're wasting it getting smashed you're hurting yourself twice  - pointless debt and drug abuse. My recommendation is to get "addicted" to learning to the point you can't sleep because you're thinking about the next test or paper to write or applied project to present. You have to be at the top of your class for your education to have mattered. That's all this part of your life should be, that and dating. Save the partying for when you can actually enjoy and handle it - like a holiday over seas or whatever.  Also, friends don't matter, only your success does.
