I haven't read through this entire thread.. but I do believe colonics to be VERY beneficial. Unfortunately, my first colonic stirred up too many toxins, and I got really ill afterwards.. but 2 weeks later, I had another colonic, and things got much better from there.. It's true that you can wipe out some beneficial flora this way, so its important to repopulate. There was one colonic that I got hot/feverish, which is the same feeling I get when I was feeding candida... but.. it was important for me to flush out the dead yeast, because it will feed the live yeast still living in the bowels. I flushed out incredible amounts.
I still do colonics once a month and I get no side effects from them...I highly recommend them.
