I finally put the pieces together and went and looked at the tea I'd been drinking. Ah-hah! Flavored Black Tea! I am sooooooo awake right now. I feel like I could so go climb a mountainous hill right now and the best part is that in spite of the fact that it's now 1:30 a.m., it's light enough out that I actually could. :)
The good news is that I'm powering through a very nice burst of productivity. The bad news is that I have a morning interview downtown that I am going to be, at best, bleary for.
Oh boy!
