Well, @jdiakiw, you do indeed exhibit a rousingly professional medical team. Congratulations on putting that together. I don't have a polycystic condition thankfully, but I had a marble-sized cyst on my chest that ruptured a few months ago. We bathed it daily and kept it protected from bacteria, but did nothing else except tweezer out pieces of the lining when I could see them. To keep my potassium levels up, I drink a cup of pure coconut water for breakfast every day and add a little later if I need additional potassium. Against that background, I simply reduce my daily coconut water in order to bring the potassium reading down. That's not much help for you, I realize, so I'll add that I tracked down a good list of potassium rich foods on the Internet and prepared myself to avoid the most fearsome of them, but it was not necessary in my case, so I lost the list and didn't worry about it. Let me know if you want me to try to track it down and pass it along. Martin
