Yes, there are many posts on this forum from people who have been told they have Gallstones
and needed surgery IMMEDIATELY!
They did the flush and avoided surgery.
Somewhere, way back in the archives, you will find a story of someone who was in the hospital to have the surgery the nest day. A friend brought the liver cleanse to the hospital, the person agreed to do the cleanse and passed stones and avoided surgery. Honest!
Have a great day!
