Hi Doug,
I certainly hope that you've found the trigger for your gallstones. For me, it seems to be totally random. I've been doing gallstone flushes for years and that helps tremendously. I recently came across an article that may be helpful...it's not as much about foots you shouldn't eat as much as it is foods to eat... Hope this helps and best of luck!
