The one thing that wasn't too clear---Did you complete a kidney flush or a liver/gallbladder flush? A liver/gallbladder flush takes MANY flushes before you will be stone free. Gallstones are full of toxins, too.
Also, a colon flush would take you months to complete. Have you tried liquid Bentonite mixed with psyllium husks? It's an excellant flush that pulls years of "gunk" out of your system.
