I've done the cleanse twice so far.

It can be rough but it's supposed to be a good detox and you usually loose a *small* amount of weight with it. The rough part is not hunger...I was never hungry on the MC but the stuff that comes out of your body can be pretty fierce.

Of course, like anything else there is a tribe about it. They have a link to the instructions on the tribe page:

And here's a funny journal of one woman's experience with the MC:
