I did 7 of Hulda Clark 's liver/gallbladder flushes and 7 of Dr. Schulze 's over 4 months before I finally gave in and had my gallbladder out. I got out lots of stones and cups of gravel, but still had lots of pain. The surgery went great, and no pain at all since then! I was surprised that Andrea Moritz mentioned in one posting that his wife has had gallbladder problems for 23 years. I would think that if his flushes (like the Hulda Clark one) worked, she wouldn't have problems any more.
