Having had several colonics, would have them performed weekly if I could afford it. Perhaps the reason your friend was so exhausted after colonics is due to the high toxicity they had in their system. When we start cleaning out bodies, the toxins become unleashed, causing very low energy, even flu like symptoms. I know, I have been there. Just found out about parasites this spring and have been dealing with them. coffee enemas helped remove the dead worms out of my body. Have her keep eating healthy, take probiotics and keep up with the cleaning of the colon. I once read that death starts in the colon. Due to our eating habits, many of us have come to realize how unclean our body is and am taking great strides forward to get back on track.
