Ragweed, great spikes of it, and sheaves of goldenrod, grew in the field beside my childhood home. Aside from the odd sneeze, it didn't bother me a bit.
Today, in what one would expect to be the less perilous lands of the arguably-misnamed Bloomfield, my sinuses are in the process of trying to kill me. Their primary tactic is dehydration; they hope to desiccate me slowly through post-nasal drip. I fight back with determination and generic Zyrtec (available very economically from that evil big box retailer that nobody admits to shopping at). It works pretty well, except for how it basically renders me unconscious. And frankly, who wants to be fully alert during a sinus headache?
