My thought would be don't do it. Eight months after my daughter was born, I ended up in the hospital and almost died from severe depletion of natural flora and fauna in my colon after being prescribed too many antibiotics after an ear infection. A colon cleanse can do the same thing. Our colons are cleansed every day by a diet of high fiber. The idea that we need to have one is just a bad marketing idea by people who want to make money off of our fears.
