HI NANCY!
Sorry, I have been so busy, haven't forgotten about you!
I have finished the treatment! 42 days are gone already- so quick I can't believe it. I'm amazed at how excellent I still feel, and I'm so grateful that such a cure was discovered. I did experience sharp pains initially, but they subsided. I don't think there are any side effects of Epsom Salts , I think the pains have more to do with the system cleansing itself. It's not the Epsom Salts alone that cleanse, but the entire diet. Recommend that your husband tries the diet for a week or two if he wants a good cleanse. I don't know re kidney function. I had some pain initially, but that left after a week or two. I am used to having kidney infections on a regular basis, but I have not had any such thing both during and now after the treatment. I only wish I had known about this cure earlier! Well, take care & good luck.
Bel.
