The liver flush is one of the strongest body cleansing you can do. It puts a real strain on the liver, which I why some, (andy cutler), recommend people with mercury issues do not liver flush, because it put the already stressed liver under serious stress.
My lower back also used to hurt when i did them, which I took to be my kidney under stress too.
They say you need to get out minimum 2,000 stones to be clear.
The only way to know if u clear of stones is to flush 3 times with zero stones.
Wait minimum 2 weeks between flushes.
Maybe try an Epsom salt flush? Bowel cleanse? Otherwise the curezone liver flush support forum is very big and plenty of cool people will know what to do.
