there are people here with far more experience than me (I only know, so far, what I've read).
Have you done all the steps leading up to Liver Flushing including kidney cleanse, parasite cleanse and then lots of apple juice just prior to liver flush?
Also, several messages have talked about herbs/roots: "gold coin grass" and "break-stone" (a root, I think) which help dissolve or break up the stones.
Hope you're not in too much pain & can make this work.
