When you don't want to pay for a colonic, you can do it at home with a colema board.
A lot of people do that because if you don't live near a city or California you can't find anything nearby. The price of a colemaboard is about the cost of 2 colonics, so you save a lot of money.
You have to google it or you can also find them on e-bay. You can check http://www.amenhealth.com to see a picture. They used to have a video but it does not seem to work anymore.
Check in the FAQ part of the bowelcleanse forum about colonics etc.
