Apparently, it's a very bad allergy season across most of North America. The delayed spring created a sort of "pollen bomb," as everything bloomed and blossomed simultaneously.
I'm certainly feeling it. I'm practically freebasing antihistamines.
Dust is also a huge problem for me, so we have a high quality air purifier. To battle mites, our mattresses are enclosed in plastic and we put our pillows in the freezer for 24 hours, once a month, to kill the little rotters.
Hang in there. I know it can be miserable. Yesterday, I said, "If I have to blow my nose one more time, I'm doing it with dynamite."
