I've heard but cannot verify that eating more potassium will make it smell bad again. That is, that a mineral deficiency may cause some things to smell good that otherwise wouldn't.
I know someone who had an intensely positive reaction to wet, musky smells (think basements, dirt, old carpets, that sort of thing). Their doctor put them on vitamins for a separate issue and the attraction went completely away.
Funny how seemingly unrelated stuff tells you something as fundamental as this about someone. I wonder what other deep secrets about our lives we're exposing that we're completely unaware of by just being ourselves.
