The whole process was seven days. The first three days you are making changes in your diet and finding the number of "digestive stimulator" pills you need to take to have at least three bowel movements a day. The remaining days require a juice fast and a more aggressive dosage of the toxin absorber and digestive stimulator. I started seeing the mucoid plaque on the first day of the juice fast.
In case you don't want to embark on the juice fast, they give directions on a 21-day cleanse where you just make tweaks to your diet to help promote cleansing. They do stress that the best results come with the fast. As a note on this....I had absolutely no problems with the fast. I had never fasted before and at no point was I hungry or tired or weak. I did high-heat yoga every day during the fast and felt awesome. I actually was pleasantly surprised at how easy it was to go without eating for that long. If anyone is having reservations about the fasting I would highly recommend you at least try it and see how you feel.
