I think alot of people on this forum are not doing "The Master Cleanse". They are doing a modified version of the Master-Cleanse but not the real MC. You hear alot about doing other cleanses, mostly the PB shakes with the MC, which is really not the real thing. Mr. Burroughs developed this system for a reason and that's to give the digestive system a huge break by not causing perastaltic contractions of the intestines to start digestion. You can't even chew gum on the cleanse! By putting ANYTHING into the mouth other than the lemonade will cause an adverse reaction, one other than the one Stanley intended. This IS The Master Cleanse not a modivied version, so when on this cleanse, only the recommended should go in and afterwards other cleanses can be done. I thought we should cleanse only one part of the body at a time. Cleansing can be a long and involved process if needed, and so it should be, if need be. That's not to say that doing PB shakes with the Master-Cleanse is not right, it's just not
"THE Master Cleanse".
