Orange stool could mean lipid malabsorbtion -- a recent flush would explain a lack of bile. Alternatively, in my mom's case, carrot orange globs of floating oil were due to sludge. Sure enough, the following flush day a layer of green grassy bile was floating in the bowl, a few hours later 8 1cm Gallstones appeared all grouped together.
I would concentrate on prepping yourself in-between flushes with bitter herbs to increase bile pressure and synthesis. Break up the stones with apple/tart cherry juice or some malic acid. Then hours before the flush sop up the remaining oil with some fiber in the form of psyllium. This will make the flush increasingly more effective.
