Similar thing happened to me. I kept seeing the oil pulling forum and thought it was so completely bizarre that I stayed away for quite awhile. (I still haven't ventured in to the Urine forum, I'm still too scared.) But with OP'ing, eventually my curiosity took over and I had to take a peek as well.
Haven't looked back since. It's just nice knowing that if there was a contest in my area for whose teeth are the smoothest on the INSIDE -- I'd win! Grit-free and proud of it.
