Thanks guys. I've decided I will try to do the cleanse anyway, and like you suggest, just limit my intake of fluids during the hours that I must work. I started yesterday with the lemonade. It is very hot here, and I found it very refreshing. I feel great this morning, which I guess is Day 2.
I know from doing the B & P shakes that I definitely need a "private biffy" and absolute freedom to run to it when I need to.
No, I don't have an iron bladder, and I'm female so the idea of a catheter is not practical. I'm just gonna do the best I can!
