From amazon.com, Solid Gold S.E.P. (Stop Eating Poop) (3.5-oz container). One of the reviews:
Unlike the other reviewers, this product didn’t have the magic effect I had hoped for. I still feel a constant and irrepresible desire to nibble on my poop on the most inconvienient occasions. That said, I still take S.E.P. on a daily basis, because the peppermint and parsely are great at disguising my chronic bad breath.
