I don't know if this helps anyone, but my sister is a Physical Therapist and very well read, with a very natural approach to medical issues and has helped me to find some great natural alternatives to things that normally require medication. Anyway, I ran The Master Cleanse plan past her and she said it seemed that it would satisfy what was necessary in the daily diet for a short amount of time, she did not see a problem with 30 or 40 days and that the electrolyte issue short term should not be a problem. She also stressed that I needed to make sure and drink plenty of fluids. I hope all of you have a happy mother's day. I will add that when I told one of my friends what I was doing she asked me if I got the plan from a witch doctor so not everyone is supportive or thinks it is good for me!
