Hi Fil, thank you for posting. I hadn't heard from anyone by Saturday so I went ahead and flushed again, making that two nights in a row. Oddly, I didn't pass a single thing. Well, maybe a few small itty pieces of green but no recognizable stones. My first flush I passed lots and lots, even big ones as much as 1/2" in diameter, but this time nada. Even with the extra oil. Perhaps I didn't wait long enough between cleanses? It's been two weeks. Thanks again for your reply. CAT
