Ha. I just did this. I made it 11 day and then I finally broke the fast. I drank green, red, orange juices and lots of water. I didn't use enemas. I had a bowel movemet every few days.
I juiced lettuse, spinach, kale, green peppers, cucumbers, pears, apples, pineapples, watermelon, cherries, strawberries, blueberries, mangoes. Oh, and carrots and ginger. Lots of stuff. I read some of the blogs on juice feasting.com
I lost 12 pounds. Gained 1 the first day I ate and today is my third of fast.
Good luck. The first couple of days are killer but once you get over it, it's easy to continue. I could see myself doing this occasionally but I definitely felt deprived in the end. I broke my fast by eating sushi...I was kinda starved for protein.
