I am glad it is working for you I started more than 10 years ago, did enema's, actually I bought a colema board and used that, which is closer to a colonic. Never did the stethoscope or
massager but knew about it from Uny (natural healing).
Did a lot of different supplements including Planetary stone free. My problems were different I have a calcified stone and I still have it but the cleanses improved my general health.
Most flushes did not show stones, but as long I saw some bile I was satisfied I figured I got rid off toxins.
At least it got me off 6 prescription drugs who the doctor told me I had to take the rest of my life. The other thing that helped me was Oxypowder because that also cleanses the small intestines what helps with digestion.
