Depends on the person. Every person is different; my family packs trash we forgot to take out in our intestines. Some folks pack it in the arteries. I can't tell you which is worse!
A serious Colon Cleanse is an odyssey. There are many things you can do, and I am posting my ten day deep cleanse just to give people an idea what is possible. With mucho fasting and colonics I was able to remove years of antique gunk, and yes, I was clean two years ago. I know this from colonics and their results, and the radiant good health I experienced!
In ten days I lost 4" off my waist! It was like an anal tummy tuck!!! That was all stuff I had managed to squirrel away over the past two years! My excellent therapist tells me I could benefit greatly from a cleanse this deep annually. Sounds good to me! I am in this for life!
A professional colonic is a wonderful diagnostic tool for the state of your colon, as well as removing bunches of trash it would take months to remove otherwise. Every Master-Cleanse I have done, every juice fast, has included at least one colonic.
The main thing is to be aware of what you are carrying around in the way of toxic waste, and where you are carrying it. Then you can focus intelligently to remove it ASAP, and to keep it out!
I'm still at it! It's a lifetime commitment for me.
