I am considering it myself. I am considering it after a two week intense Bowel Cleanse (Dr. Shulze Intestinal Formula's 1 & 2), and immediately after a kidney cleanse/dissolve routine - 5 day juice fast.
I am thinking perhaps of doing the Clark Regimine for the first part, and moving everything down an hour earlier, and then adding the 4 ounces an hour of Olive Oil/Grapefruit Juice for the next 3 hours on the hour following. This is my current speculation.
If and when I follow through with this method, I too will post the results.
It would be great to hear from you if you try this method, and how it does for you.
