You saw John of God!? How COOOLLL!!! I saw something about him on T.V. a while back...thanks for reminding me of him:)
With the okrapepsin, make sure to eat a non-mucus forming diet...NO DAIRY! VERY important. EASY on the grains, espc. wheat. It is ideal to eat vegan while taking it, espc. raw food. You don't want to compound the mucus issue while you're trying to clear it up...
