By far the best Herbal, all-natural diuretic I have ever used and will continue to use for upcoming shows and shoots (I have tried a few out there) is PVL's Watertight!!!! I love it and it gets you dry! There is no cramping or anything and it actually has beneficial properties to it other than just suck-ing the water out of you It is one of the only ones that I have found that doesn't use caffeine in it either.
