Retronerd, that's so awesome! Are the pains gone, too?
I did my 14th flush 3 days ago, and I too passed 2 golf ball sized stones! They were pale beige on the outside, kind of sandy, but pea green in the middle, and smushy. I didn't pass them for almost 24 hours...they were taking the scenic route, I think. Bye-bye, golf balls!
