I don't think you have taken steps backward. It is more likely that your colonic has opened up some old waste capsules. When gases are generated as a result of colonics, it is old waste that is being softened up and is digested by waste-destroying bacteria. The byproduct of that action is gas. It discontinues when the bacteria have done their job. Removing these old pockets of waste can save a person form major colon problems. So I believe you have taken a step forward.
