I'm on the Oxypowder Colon Cleanse right now, and after I finish I be going straight into the liver flush. I will be doing the Liver Flush from Andreas Moritz 's book.

I read that it's important to clean the colon before and after, even recommended to have a colonic done afterwards. I looked up colonic prices around my area and they seem rather high... can I instead, after the liver flush, just do another round of Oxypowder colon cleansing, or is it really a MUST I have a colonic done afterwards?
