Anyone else lose all focus when switching from daylight to standard time?

I know typically people are happy with falling back one hour with this time change, but regardless which time change is happening I seem to lose all focus and drive at work for a good 2-4 weeks.

This happens when I travel as well and but my friends and family generally seem not to mind change in time.

Anyone have any interesting information on this? I’ve searched far and wide but it usually results in numerous (worthless) lighthearted “here’s what to expect”-style news articles.
