your plan is sound but sip water dont drink it all. I was using diuretics before but stopped now, I try to come in dry for the show and use only herbal diuretics and teas, otherwise I came in flat a few times to shows and cramps sucked. Lasix was horrible for me, super flat disaster.
I too want to see how you do, can you log your show? and post show plan?
EF would love a log from you.
