Right now, the bedtime is a problem - revenge bedtime procrastination + everyone getting used to me doing extra work overnight during some more busy times (I work remotely, so sometimes I handle kid emergencies during the day) + various other issues --> even if I had an "insta-sleep" pill, I'd have hard time getting myself to take it before 02:00.
A SAD lamp is something I'd like to try in general, maybe it'll improve my overall mood or something. I seem to function best in either near-complete darkness (i.e. only light being the screen, indicator LEDs and some street lamps in the distance outside), or very bright environments. The average brightness people I know keep at home makes me instantly sleepy, and I spend most of my cognitive resources on forcing myself to stay awake.
