Snippy? Maybe a little. Foggy, edging slightly toward headache? Well, yes, now that you ask. Water? Ozarka. I wonder if it's cheaper than Dasani. Wordy? Sadly, still, yes. Productive? Never as productive as I would like (and therefore, little change). Ready for a Diet Coke? No, thank you. Exercise? not yet, but I will. Tomorrow? Busy. Tomorrow? Caffeine-free.
