I've probably passed thousands of stones during my liver flushes, but a few of the flushes produced no stones. I don't flush that often any more, usually only when mercury symptoms and chronic fatigue flare up.
I pondered the possibility that my chronic fatigue might be lyme or a similar bacteria. I stumbled onto some information about teasel herb. I ordered a bottle of teasel root tincture and it helps chronic fatigue a lot more than liver flushing.
The caffeine in a coffee enema has a completely different effect than drinking the coffee, and it's totally safe and non-addictive.
Don't pay much attention to the times and seasons of symptoms. I've had so many extreme symptoms from various sources until recently I never was able to relate it to a particular pattern. This is something I need to pay closer attention to.
