Things smell funny lately

[cjsmith]

For the past few days or maybe a week, many things have smelled... odd... to me. On Tuesday, Spaghetti-Os smelled like rosemary. A cheeseburger smelled like fresh cut paper (or cardboard?) Wednesday, and even more disturbingly, last night a cheeseburger smelled like nothing at all! It had mustard on it. How can I not smell at least the mustard? Potato chips and french fries both smell somewhat sour, but they taste okay. My body's waste products smell like old fish; conversely, bad breath smells fecal. Today, driving in traffic, I was sure I should be smelling icky car exhaust smells, but what my nose reported was a pot of freshly drained pasta.

This is mildly disturbing. What is going on with my body? Does this have something to do with the new nutritional supplements I just started? I am sure at least the bit about my body's waste products does indeed relate to that; among other things, I'm taking 1.8g of "marine lipid concentrate", whatever that may be, twice a day. But what's going on with my olfactory sense?
