90 drops of the Ultraphos in a quart of apple cider and sip it all day. Do a quart a day for 3 days. On the evening of the third day, do the coke flush. I had stones that were 2 inches long that came out. Usually the sweating and nausea I had meant that my bile duct wasn't open enough to let the stuff pass. This happened to me with the Clark flush when something got stuck in the bile duct. Then I had the pain that went with having something getting stuck in the bile duct.
