I think the really solution is to reduce the amount sodium so that you do not need to sweat it out. I have had several follow up visits by a nurse since I got out of the hospital.
She wants me to try and stay below 140 mg.of sodium per serving which is hard to do with todays processed foods . Example salad dressing most have 250-400 mg of sodium per serving.
She suggest diluting them using vinegar (rice wine vinegar). Half bottle of salad dressing topped up with the vinegar reduce the sodium in half. I tried it with Kraft Catalina and it is real good
