I was surprised by the puffed wheat. Really, I don't eat any of those foods except for the occasional beer, but I only drink one in a 24 hour period because of my ulcer history. Coffee however, is my downfall, though I don't drink any in the evening or night.
That's interesting. Doctors used to test for diabetes by tasting and smelling urine. If it was sweet it means your body is passing sugars and not progressing them. Not that that has any implications for you of course. I too have noticed certain things can make mine smell sweet.
