I know that ego-depletion *qua* ego-depletion is not a real effect, and so I wasn't sure what managing "energy" really even meant any more. And this little self-experiment is in line with that; this is not fixed by a little glucose or a good night's sleep, which *would* fix it under a simplistic "ego-depletion" theory; it's a longer-term psychological effect that implicates activation energy over longer periods of time. Not sure if there's literature on this but the effect is real for me.
