Potassium controls cardiac output, taking potassium when you don't need it is asking for trouble. Potassium is not the problem in 99% of cases it is low sodium. Adding sodium back in the day of the show will do many wonderful things...increase blood pressure(which will be very low due to water and sodium loss) thus increasing vascularity. Vascularity comes form blood pressure not loading up on sugar. Unless you are running a loop diuretic like Lasix there is no need for potassium.
