Dear David: Most drug stores will have some potassium, but they are often mixed in Oral Rehydration packs, in the form of potassium chloride, potassium citrate, and sometimes potassium bicarbonate. Citrates and bicarbonates are quite closely related and can be used with each other. I must warn you, that when using potassium make sure it is 9 parts sodium and 1 parts potasssium. That means 9 parts sodium bicarbonates and 1 part potassium bicarbonate (or potassium citrate). You can go to a drug store and ask them the following brand: K+Care ET, K-Effervescent, K-Vescent. Large drug stores should carry them. In the even you get nauseated from accidental dosage of taking too much potassium, the cure is extremely simple: take 1/2 teaspoon - 1 teaspoon of sea salt or salt, should that happen. The nauseation will be gone in a matter of minutes.
