I'm crashed. Don't think it's PEM. I'm wondering if sudden hayfever could have caused this nasty episode. I haven't had hayfever for a decade because of living abroad. Then got hit with a horrible attack a couple of weeks ago. I'm using a steroid nasal spray and Benadryl to control it, but my eyes are still a bit itchy and I'm a bit sneezy still. I was doing SO well at the time. Out and about, sleeping better, brain functioning more. But now I've been weak as a kitten for a week, can't absorb information at all, and it's getting worse. Life giveth, and life taketh away. But I'm wondering if the allergic reaction thing has set off a cascade effect?
