Yes, I have done colonics...make sure you have a good/qualified technician and that they use a closed system!
Also, be sure to suppliment with healthy flora afterwards...your technician should recommend a good suppliment or try eating foods with naturally occuring "healthy bacteria" There are some good recipes for that on http://www.raw-food-for-families.com
Overall I think it is a good idea, you just want to make sure that the person is qualified, you do enough treatments, and that you re-build the healthy bacteria in the colon...and take some pepermint oil in case you get nausiated...I did the very first time.
Let us know how it goes!
