Master Cleanse Tracking: Has anyone done this?

Hello all,

A few years ago I started to do the Master Cleanse once per year. Because I already eat pretty clean, I don't lose that much weight on the cleanse (meaning my digestive system doesn't have a lot of un-processed waste to get rid of), but I am not sure how it will work for calories earned/burned here on MFP.

Have any of you done the cleanse while tracking on MFP?? I did search and it is in the database with the correct amount of calories. I am just curious as to how any of you have done this. Do you drink back calories earned in the cleanse??

(Side note: because of gastric issues I do modify the cleanse and use fresh squeezed juices as well as greens and protein powders via doctor's orders)
