Still on the fence about the flush. At least now I dont have to worry about the 2.4 cm stone getting stuck on the way out. Maybe after I get my constipation problem under control I will flush. Currently i only go every 3-4 days and I know I am clogged up. 6months ago I had a series of 6 colonics to get unclogged. I eat fiber, fruit, etc, but still only go ever 3-4 days. I just purchased some flax seed and a grinder gonna try that next.
