I would suggest to go on with flushing. It might be quite possible that despite your sucessful flushes that there a still lots of stones in your liver.
Also keep n mind that an Liver-Flush is an operation without knife.
After having released stones the liver can be very tender for wuite a while.
Alternately, it might also be possible that you GB is sort of "lazy" and does not contract properly. What can you do.
I have similar problems and my "magic bullet" is either olive oil (1 to 2 tblspoons) first thing in the morning or a mix of lemon juice a olive oil also first thing in the morning.
Furthermore I would recommend to use tumeric in your food. This root is really helpful for the liver and tastes good. You can put it into a pasta meal or into cooked or fried veggies. A mix of powered ginger, sone cayenne plus tumeric makes delicious meals and helps the liver even more.
