Hi Chaw, I'm glad you found this cleanse; hopefully you too would agree that it has saved you an awful lot of inconvenience of gallbladder surgery.
The reason I'm responding though is that I just wanted to let you know that there is a very effective chinese herbal tincture called gold coin grass(GCG)(Chin Chien Tsao in chinese) which is used to partially dissolve gallstone so that they can easily pass through the ducts. I recommend that you take half a litre of this tincture(1 table spoon each morning 30 mins before breakfast on an empty stomach.) Should you wish to read more about it, please go to http://www.sensiblehealth.com/#Topic_Gallbladder (it's quite a long page; I'd advise you to print it out and read patiently 'cause it's really worth it).
I think this should dramatically improve your future flushes.
