Well, I can't believe what is coming out of my daughter. She Has a whole pile of green and tan stones. Much more than I have and she is only 19? How does this happen. I am 52 and we did the same exact prep and flush. Ours went at a different pace, but I was just amazed at what she passed, and she's not even done yet. She has had a pouchy belly her entire life, could she just have been born with this tendancy to produce stones?
