Weight Loss Bet help

Options
I made a small wager with 3 other buddies on Jan 4th which will end on Apr 4th, a week away. The money is far less important than actually beating my main competion

I am very happy with my progress, I have lost 39lbs (started at 244, down to 205). The 2nd place guy has also done very well, he is currently at -33lbs (started at 247). I have accomplished the weight loss thanks to counting calories with mfp and some sporadic walking/jogging.

My question is that I have been consistently weighing myself in the mornings, but the final weigh in will be in the evening. I am expecting to have a higher weight at the weigh in than I am used to seeing in my morning weights and would like to hear some suggestions on how to approach the last couple of days before weigh in. Any suggestions on diet the last couple days?

I am not looking for anything crazy, but curious if i should be avoiding anything in particular or if i should try have some extra portions of another.
