Sniffing Out the Problem

Remember how I had that nose issue about half a year ago? Well, very mysteriously, it just went away by itself. Maybe it knew I was posting for advice about it, got freaked, and left.

And then decided to move back in again.
I smelled it again just two days ago.
Yesterday, it seemed to fade a bit.
But it smells like it's back again today.

I have a feeling that it's related to my diet, or is a cryptic symptom of my health in some way. My current hypotheses on this are:

1. Sauce.

Three days ago, I had potstickers from a popular joint just around the corner from my work. I have these pretty often, but this time I had it with chili bean sauce (豆瓣醬) -- I used to have this a lot, but some months ago, traded it in for a garlic soy sauce and/or sweet vinegar instead. Lo and behold, the next day, I guess it worked into my system and the nose thing came back!

2. Health.

I've been sick for a while in November and December -- a really nasty virus has pretty much hit everyone I know in some time or another this winter season -- and even now, we're trying hard to shake that last 5% that just won't go away. I don't remember if I was sick back in July 2007, but maybe it's related to my health at the moment.

3. Diet.

A broader generalization, perhaps it's just my diet. Or, maybe the two are related: food and health. When I'm sick or getting sick, my body has cravings for different types of foods (mainly carb-heavy stuff). So perhaps my current diet has a surplus or a deficiency in something, and that's giving me this "reminder" in my olfactory senses?

I dunno. Any thoughts or hints?
