Hey i just had a thought, my shows are Oct 19th and Nov 02nd, which means they each are exactly 1 week before yours. I will be posting all of my last minute prep on here and diuretics and water cutting and the results of how it all works out. You can have a look at what i will do and you will be left with a decission to either follow something similar or not...just thought that will help you out a bit the week before the show.
Good Luck...XXL
