I'm not going to push this tonight (big day tomorrow) but either it did something impressive or I have one heck of a placebo effect.

Banished the freezing that would have me well in its grip by now. Feel good, too. Probably due to getting out of that shower.

If this is a real effect, it would at the very least be a handy way of improving those first hours of the day and last ones at night.

Is it releasing extra noradrenaline from finite reserves or is it producing extra and adding to them? Or is it affecting the receptors or something similar? Lots of questions. But I can report that it gained me an hour of functional time on this attempt.
