Do you have any symptoms of anemia? ever been diagnosed with anemia?
I'd say keep up with the chinese bitters and even look into getting Coptis. Since you are taking in enough oil to make the liver release bile, if the stools are pale there can only be two reasons: either there isn't much bilirubin because you have anemia, or there isn't much bile because your liver is weak or congested. (is that three reasons? LOL!)
Let the CB do its work for 2-4 weeks then do another flush. :) You can I think safely take liquid phosfood and apple juice at the same time as CB and Coptis to keep dissolving stones. The GCG shouldn't be taken with CB.
