If you've got any significant bowel and especially liver problems, Julia Chang's protocol is NOT for you. I started out with it. Didn't work. Made me sick. She had good luck with it, but makes no real promises for anybody else. It CAN'T work because the order of cleansing isn't followed--colon, liver, blood,lymph and tissues last. Can't argue with it. it's a product of Guytons Physiology and based on the physics of how the body works. Do it any other any and you're skunked before you begin.
I went with the anti-parasitic of Barefoot's http://www.oldfasionedspices.com and stayed on it for 6 years twice a day, did a Colon Cleanse that took me 6.5 years of doing it off and on with adding #2 formula, the #1 formula ALL the time, and Liver Flushes over a period of 5.5 years before I got all the stones out of my liver. That DID work. It's a program geared for the terminal, and will work for everybody in between.
I am now working with other terminal cancer people that it is working on,too. How many times do you have to see and prove that a process works before you "believe" it does???
