yes. I started doing the pb shakes on the tenth day of the master cleanse. I did the master cleanse/lemonade fast for 20 days. This was in november. I again did a 10 day master cleanse fast and used the pb shake the entire time also. This one I started on jan. 2. I am still doing the pb shakes and eating normally ( i must admit i am a junk food addict) but have cut way back and am eating lots and lots of organic raw vegetables and fruit such as apples, pears, and grapes. I drink lemon in my water all day also and do not drink diet coke or coffee anymore. Just herbal teas and water and the pineapple juice and apple cider juice. I know the pineapple juice is probably not the ideal juice but it taste so good and i only drink it with the pb shakes and thats it. The ropey stuff that comes out everyday is very very long but it is not dark in color at all so it probably is newer (old) waste? (smile) whatever it is, i will tell you this.... i used to have one hard dark clay like clumps of tiny balls as a bowel movement just once a week and about killed myself straining to have that. This is like a miricle to me to be able to even go to the bathroom every single day. I do only have one movement and it is always in the morning. Sometimes according to what i have eaten I will have a movement at night. I would love to have three a day!!!! (smile). Sherry
