If you don't release it, you keep it.

The number of sessions needed depend on the goal of the individual.

Yes, one session will empty part of the colon. However, from our experience in assisting clients, we found one does not normally start releasing the old, long held waste until the 5th or 6th session.

If you are new to colon hydrotherapy just come in, try one session and see what it does for you.
