I'm going to reply to myself because you all have helped me to solve the mystery. My once stellar response to my diet has changed because:
I started Liver Flushing last summer, stopped after 3 or 4, this changed my reaction to my high raw fruit/greens diet and caused my health to spiral downward over the next year.
Now, this summer, I have liver flushed 2 times, and digestion has plummeted further. Liver Flushing is not to be delayed once begun, so even though I am tired out by them, I can't put off the flushes.
This is my conclusion and thank you to everyone who spurred a very interesting discussion that helped me unravel what should have been obvious to me to begin with.
