The Master-Cleanse has been known to cause gall stones. Based on what I've read, it is recommended that you Liver Flush before and after MC. You should let your system get back to normal before doing it.
I'm ending this Master-Cleanse Sat (day 20). Once I have normal bowel movements, I plan to start a parasite cleans for 30 days, then the liver flush.
I am really looking forward to the orange juice. It's funny, I really haven't been hungry since the first couple of days, UNTIL I decided to stop. Now I'm hungry!! Talk about it being in your head!!! :)
