The weather-caster noted this morning that ragweed pollen and mold were "uncommonly high."

Ah, so that explains it.

Unlike "normal" allergy sufferers - who sneeze and get runny noses and cough and in general have physical symptoms, I get tired. And dysphoric. And lose some of my generally bouncy and resilient demeanor - going from Tigger to Eeyore in the course of a few hours.

The thing is, unlike a lot of minor health-related things, knowing what it is doesn't help make it better.

I may need to invest in a new air filter. I used one for years (it was my night-time white noise source as well) but then the company that made it stopped making the filters, so I got rid of it.
