My first Liver Flush came from my chiropractor. It called for 10 days of apples, apple juice and veggie broth at night. Everyday 1\3 cup olive oil was drunk . Daily coffee enemas were part of the protocol . After 7 days stones starter coming out. This lasted 3 days. I discovered Curezone when looking for an easier way to flush. Coffee? A cup in the morning, but no caffine near the time to flush.
