You are obviously desperate to prop up your misinformation. Within 10 to 15 minute a have a bowel movement this clears the bowel of all fecal matter, in less then an hour, 25 to 45 minutes yes minutes I have on occasion produced stones ! Your conjuring up the term fecal stones is hilarious and just something you made up to promote your lies, you are transparent as glass HV, and only put off or delay healing in so many who could benefit from these flushes, you should be ashamed of yourself.
