Making Preparations for WLS

Getting a little nervous and excited.  I go for my finaly consultation on Tuesday. 
I am trying to make a decision. Should I go ahead and have the surgery at the first available appointment or should I wait until August.  Why the indecision??? I have such a busy summer planned....Camp Funshine, VBS, Fun Day, Mary Kay Seminar in Dallas, and hopefully and little vacation some where in between.
Any advice from those post-op peeps would be appreciated.   Is it better to be so busy that you don't have to think so much about things or wait until you can solely concentrate on what is happening?
