Initially I attributed my sleeplessness to something else. Perhaps there was a lil bit of that factored in, but then I remembered that I had not one, but two glasses of sweet tea yesterday. Plus I had a brownie at dinner. I've gone almost a month without coffee or other caffeinated sodas. I've had wee bits of chocolate here and there. In other words, I gave myself the equivalent of an intravenous slow drip of caffeine. I'm sure I'll have the bags under my eyes, later, to prove it.
Note to self, stay away from the Sweet Tea.
