Don't forget to set your circadian clocks back.
Harder said than done.
I don't like the shorter hours of daylight. It usually means I go to work when it is dark and leave when it is dark. I like the longer days of sunlight. I guess the shorter days make me SAD, so maybe I should take the advice of this article and plan winter vacations to sunny climates. :-)
Luckily I don't have problems to a clinical level as some appear to, but I do like my sunlight.
