Hi ivygreen,if you haven't already visited S.A. Wilsons organic coffee website, be sure to go there at http://www.sawilsons.com
. They have the most extensive information on coffee enemas that I have found anywhere.
Also, understand the benefits and differences between colon hydrotherapy (colonics), cleansing enemas, and coffee enemas. Cleansing enemas and colonics evacuate waste matter from the large intestine, whereas the purpose of a coffee enema is to cleanse the liver.
If you will be using enemas in place of a colonic, you would probably want to take 2 or 3 cleansing enemas to try to eliminate fecal waste and toxins from your colon.
I'm including some links with more information on colonics and enemas:
