'Cause it's overcast pretty much everywhere, and you ran out of caffeine?
I'm sort of awake, but then I went to bed early, got up fairly early, and had a big breakfast and plenty of coffee.
Actually it's sunny here. I went to bed at eleven... couldn't sleep right away, of course, I'd only finished my exercise at ten and that always winds me up.
I skipped breakfast but that's nothing new. Must just be Tuesday.
