white as snow + edit
I am the only one here, as far as I can tell, with a 27cm stone.
I have had it since 2003 after doing a lot of flushes and taken every supplement mentioned on CZ it is still there.
In general I am doing ok, a few times a year it acts up but right away I take 1 tbs of
Epsom Salts and I am fine again in 20 minutes.
My stone was originally stuck in the gallbladder neck and I had inflammation and the wall had thickened to 42mm (normal 3 mm).
After 10 months I had another ultrasound and the stone was free floating, inflammation gone and wall back to normal.
Edit: I wonder if you drink water after 2 pm, that is important though it is part of
Andreas Moritz flush and not Clark's, but over the years some people got dehydrated
and did not feel well. I am just guessing but may be it will help with your headaches.
