When do you stop doing liver cleanses?

I have done 3 successful cleanses within 2 months. Although I feel positive about them and the good results that followed, I have still had a gallbladder pain attack about a week or two after each cleanse, sometimes when I had not been overdoing the fatty foods at all. It is usually my cue to do another cleanse.
I have been imagining that after each cleanse there is an invasion of more stones and sludge from further back and so on.
This prompts me to ask 'How many cleanses should one expect to do in order to be free of these periodic attacks'. Is it possible to be 'clean'. When I read about people who have done 16 cleanses I wonder if there is a cut off point? Tweet
