I'm wondering if it's not something environmental? Something in your workplace or home?
I dunno...hmmm...I'm tired and maybe not making much sense (or even less sense than usual.) Also, I'm dreadfully behind in what's going on in the Hole since my absence.
Yeah, there are numerous irritants here. We've had the bathroom remodeled (the subflooring was rotting out). The animals, the leaves. We're moving furniture and frap around so there's extra dust...
None of that is helping. I've just never had anything linger like this.
