Actually the same thing happens to my wife and to me in one occasion, the problem might be that your liver is so congested that you need drink some chinese herbs to decongest the liver like chinese bitters or swidish bitters, take them for 10 days then get some stones softener like malic acid, and then go for the liver flush, then you will have a very succesful liver flush. Also you have to sort of fast on fats for at least two days before Liver Flush to load the gallbladder and liver on bile so that when you go with the Liver Flush the liver will push out lot of bile pushing in the way out also stones.
