I'm wondering how in the world it travelled through your intesinal track and made its exit so fast. My last flush (the 6th) I didn't take epsoms for the first time. Even though I know I had a decent flush (could feel it during the night), it wasn't nearly so rewarding from a psychological standpoint because it took a couple days before anything "showed up". And even then it was convoluted with other stuff.
I'm not questioning what you said. I really want to know.
