The colonics you did, were they of the Colema type? When you evacuated, was it only clear water that came out?
At this point, if I were you, I would consider trying a full bag soapsuds enema. Mix a bar of Ivory soap in a pitcher or bowl of warm (103 degrees F) pure water until it is milky in color. Use Ivory bar soap only, DO NOT use Ivory liquid, it is far too harsh for internal colon use!
