Query: Disappointed

The book made sense to me, and I was excited to start the detox program. I faithfully followed the diet guidelines for the week leading up to the fast, then followed the fast to the letter. This included adding the fiber to the first and last drink of the day. Results? I lost two pounds by the next morning. Not the 3 to 5 pounds expected. But what disappointed me most was that I do not feel detoxed. I did not have a bowel movement during the 1 day juice fast, or the next day, or the next. I am bound up and in misery. I probably will have gained all the weight back by tomorrow and feel worse than before. I am following the three day sequel guidelines to the fast, but it is not working for me. I think this book is just another gimmick. I wish I never bought the book.
