Anyone ever try the Master Cleanse?

The Master Cleanse is not a colonic. It is a flavored water that you drink while fasting. It is made up of water, lemon juice, maple syrup and cayenne pepper. Beyonce recently did it and lost 20 lbs. I am thinking of trying it because all of the people I know that have done it feel amazing and lose a lot of weight. I am probably going to start it next week. So I will let you guys know how I feel and what the results are.
