Months Before Intern Year

My apologies if this has been asked before; but what should I do the months before intern year? I know most of my mentors have told me to lay back and relax while I can,not to study, and just make the best of the holiday that is fourth year. I'm finding this hard to do as intern year looms closer and closer and my brain is progressively atrophied from this whole process.

Any advice from current residents or attending?
