What is the best way or product to cleanse your colon?

I tried an enima but it didn’t really work. I want to clean out my colon so that the poop is gone and i’m not bloated anymore. I never poop. WHat are some good colon cleanse products that are reasobaly priced? I heard drinking only water and juices for a couple days can do it.
You can’t "cleanse" your colon, and products and services that claim they do are largely scams. I would suggest you see a doctor – perhaps you have a gluten intolerance or similar.
