I typically get seasonal affective disorder when the days are short.
This season I've been avoiding sunglasses when driving, it may help.

Or slightly different meds. Or behav/cog learning and/or better
(ie intentionally less stressful) environment. Most likely meds
actually.

Don't really want to do the control, its unpleasant.

I celebrate the solstices (which are also dDay/dt holidays of course).
In between those and the equinoxes, there are mid-season holy days
when dDay/dt is maximized, 90 degrees out of phase with the acxtual
maxima or minima (or equinoxes).

the rest of the "holidays" (tm) are cultural baggage trash. I do like
fireworks though.

I may burn some magnesium on the solstice, to reawaken the day
