My two cents (I was a R1 admit).
1) Keep yourself busy this weekend with stuff to do so you don't even think about it. For me it was easier because I was working on other apps for Round 2. Same goes for the day of. I scheduled several back to back meetings for that very reason.
2) Read past posts around decision day for helpful info. No they are not going to call you or release decisions early. You will get the same email as everyone else and have to login in to find out. Plan on checking at 3:30. At that point you are pretty guaranteed to find out. There is no value in obsessively refreshing the page from 11 onward. This is easier said than done and why you should keep yourself busy.
3) Stay positive regardless of the outcome--I can't emphasize this enough. If you are in great. If your are wait listed figure out a game plan to get off (it definitely happens you just have to be active). If you are dinged use this as a learning experience and try to figure out what went wrong and make sure you have a back-up plan.
Hope this helps. Feel free to PM me if you have any questions.
