having spent some time with the power off, I'll tell you what I find is generally the BEST way to deal with the lack of light at night (NOT evening)

GO TO SLEEP

Make like Ben Franklin - Early to bed, early to rise. Particularly in the summer (Hurricane season) - Wake up with the dawn (say 5:00am), work your butt off all day, by 8:30pm or so - you'll be happy to hit the rack and SLEEP
