Since we're all friends here...

I've noticed a strange thing lately when I get back from my rides. For up to a half hour after I get back there's a smell, almost more like a sensation, of ammonia in my sinuses. I don't think my body is giving off the ammonia odor (heh) - it seems to be in my sinuses. I told you this was weird.

I ran a google search to see if this was ever mentioned before - the alteratives being (a) I'm hallucinating or (b) I have some rare incurable disease - and I'm happy to report I'm neither crazy nor dying.

From what I've been able to piece together, it sometimes happens to sedentary people who start exercising (hello!). There are tons of suggestions floating around the internet as to what causes it - too much protein in the diet, too little protein, too many carbs, too few carbs - some say its a sign that you're metabolizing muscle instead of fat, others say it's the opposite. Some say it comes from not drinking enough water (which I don't think is the case for me). Eh, whatever. At least Jo Hypochondriac has nothing to fear.

or do I...?
