You know BB the reality is that the actual physical hunger really only lasts to day 3 or 4 so after that is just a mind thing and you'll be the better for it and make yourself proud if you learn to control when and what you eat. That taking control of your life/health to me is just as important as the actual physical cleasing you'll get from the MC. That's the part that will stay with you and really change your life after the Master-Cleanse is done and forgotten.
So get mad if ya gotta and use that energy to carry on and stick with it. Now kick som'dat Master-Cleanse butt!!
