Hi Water Woman, I see you're back.The M&M enema is not a hoax. The combination of the milk with protein and carbohydrates and molasses with sugars is just what the intestinal bacteria need to grow, and that is what produces the gas that gives the cramping. If you have been taking a lot of enemas and your intestinal flora count is lowered, you won't get much gas formation or cramps. The stuff about cramps and toxin release is a bunch of crap. In some people, the volume of bacteria in feces is tremendous, so those people will have a lot of gas and cramping.
Those of us here, who take regular enemas, probably will not have a lot of cramping. If cramping is what you want, look at the thread entitled enema solutions that cause cramping and look at my response. If that solution doesn't give you the most intense cramps you ever had, with great difficulty to hold, you are an android, not a human.
Also, see my MYM enema post. I rather enjoyed that enema for a number of reasons, as you'll see in my post. Originally, the reason for the milk and molasses, is that in a constipated person, the volume you need isn't great, and after retaining it a while, and because of the gas the bacteria produce, it seeps through the feces and goes moderately far up the colon compared to other solutions, thereby effecting a good bowel movement with a relatively small enema.
