Colon Cleansing before the long Water Fast.

I've asked Chrisb1 so many questions that I hesitate to ask him another. So, I'll just throw this out to everyone. I feel this forum has died, and have been wondering if it's because of me. Should I leave? I do tend to get personal at times.
Anyway, I have one more question before I go. I've decided to do it...that is to go on a long Water Fast. My short Fasts have been encouraging, and I want more of a Good Thing. However, I feel I need to clean my Colon 'before' I start. I'm not into Colonics, or Enemas, so how would you do it? The Natural Hygienic point-of-view would be to let the Fast do it, but I'd like some other views. I remember Jack Goldstein, before his 6-weeks Water Fast, eating an ungodly assortment of different foods, and healing a disabling physical condition without first cleaning his colon. So it can be done that way.
The most important thing about Water Fasting is not the fast itself, but the Diet after the fast. It's like a Cancer. You may have it treated successfully, but if you don't eliminate the Cause, it will come back to haunt you again.
Maybe I should go to the Bowel Cleansing forum, but I feel some of you here may have some ideas.....WY
