If your problems are liver/gallbladder related you can reshape stones with a few sauna sessions of hot water bottle to hold on before next flush.
If the problem is colon related - I guess you know what to do.
I discovered the way to feel stones in the gall bladder. I was doing yoga (bow - dhanurasana) with my wife and she pushed my feet back (sitting on them), forcing knees to the ground, and the rib cage up to the air. And I could feel some solid mass right in g/b. That was a week after my flash and from time to time I felt pain or discomfort in front of my right lower ribs, about half way to the solar plexus. Here is the link to yoga site if you are interested. http://www.holistic-online.com/Yoga/hol_yoga_home.htm
Also the problem could be duodenum related. In this case I could suggest to change eating habits. Try to make your last meal very light like a few apples, some greens, a kiwi fruit etc. , do not eat after 5 pm.
I know 2 good ways to clean duodenum:
long term fasting
shankha prakshalana ( complete digestive system wash )
I am planning the Liver Flush this coming weekend. I think I'll continue until I am clean.
