you have to buy in bulk and spoon it out to yourself in effective amounts.
i have potassium chloride, potassium citrate and potassium bicarbonate, all in bulk. any of them can be mixed in water and taken orally.
im still working on it myself so you just have to try a little and then try a little more. a quarter teaspoon of KCl will have the fastest effect on PB, bringing it down to normal after one or two fo those with plenty of water. the other two im playing with in other ways.
try tonys recipe using potassium bicarb instead of sodium. dont forget the taurine and edta. good stuff.
