Hopinso has given good advice. I have followed similar protocol twice now, after a 10-day and a 15-day Master-Cleanse fast. I also used organic apple juice instead of orange juice to break the fast, though I used a shorter period between fast and Liver-Flush -- one full day of diluted apple juice, then the next day have apple juice and start the LF, third day OK to break fast with some gentle solid food like a banana.
It is wonderfully productive to do the liver cleanse after a master cleanse. I got 1000 stones out the first time, kid you not! They kept coming for 2 days.
