Nonsense. I'm quite successful as a student, and I haven't stopped drinking or partying these last six years. Nor have most of my colleagues, and we are all studying a pretty demanding uni and are pretty good at it. Same goes for people who are in other fields that I know and that I regularly spend time with. Not saying all that partying and drinking is good or necessary to have a good time, but whoever says you can't have fun and be successful at the same time probably doesn't know how to party to begin with. College is awesome in many ways, and the fact that it is brutal only makes the downtime sweeter. So yeah, partying and drinking all the way.
