The decaf coffee experiment continues, though I'm allowing myself a cup of black tea or yerba mate later in the day if I really need it. And I often do. I do seem to be sleeping more of the night this week, though. I decided to quit my daily full mug of espresso when I was averaging 3.5 hours. I think job stress was the real culprit, but this is a much easier lever to pull.
Still, I did manage to get everything done yesterday despite spending the whole morning at a school show, then getting stuck with the school run unexpectedly. That was probably my Christmas miracle.
OP, how about you? Hope your dad's doing better?
