Good post RJ. I've felt strongly enough that I had undetected parasites for so long that I've treated them off and on for a year with feed store meds. These have been very helpful but haven't eliminated the problem. They make my organs hurt (which I hope is die-off), despite healthy blood tests for liver and kidney functions.
I had never heard that the rice in stool was a symptom of parasites though. I have them almost every time, and they are quite visible to the naked eye.
An increase in the white specks doesn't correllate to an increase in overall symptoms though. Does that make sense?
