I don't know as I had trouble remembering to drink 6 lemonades a day and often only managed to drink 5. I rarely felt hungry during the 31 days I fasted and if I did it was because I delayed a lemonade too long. Drinking the quart of warm salt water in the morning kept me from starting on the lemonades until late morning as they did not mix well for me. Wow, I just do not know why you are so hungry unless the problem is drinking so many makes your body process the lemonades as food and therefore perhaps preventing going into ketosis. It may just not be a good time for you to do the Master Cleanse. How long did you do this?
