unsatisfactory Liver flush

I have done 11 successful liver flush. good quantity of the stone came out every time. My gb is not in working condition. i did first Liver-Flush every month(i did total 11 flushes).
but last 2 flushes i did with 18 days interval to remove the stone As soon as possible. I did exactly with Dr. Hulda Clark Protocol.

IN Both last flushes i passed out only 2 to 3 small stone green seize and a very small amount of greenish substance. i think it was a garbage (very tiny).

although i feel very light after doing Lf.
i wanna know does the interval affects the result?
or there is any another remedy for a good result?
