Hi, the liver pop reaction through research I discovered, is actually an inaudible to the human ear sound of the stored toxins in your liver being released during a coffee enema. I guess some people listen with stethescopes. This is not needed however. i have only been doing two back to back enemas daily for a week, and I keep getting more released now from higher up. The trick now is being able to hold the second enema for more than five minutes! I'll feel a rush (which I presume to be this inaudible pop) and I immediately need to stop. Will work on holding it longer but happy with the results. Fingers crossed for some more mental stability in the weeks to come. Starting TMG by jarrow formulas as was recommended for me. Hope that will help with time.
