Every year, varying in precise date, something happens to me. My productivity drops. My sleep patterns become anywhere, anytime, for as long as possible. I'm a morning person by nature, I like to be in bed and asleep between 10 and midnight, up with the sun-ish. And then, the SAD kicks in. Long ago, when my family still lived in Maryland, my dad got crankier in the fall and winter, and my mom figured that he had Seasonal Affective Disorder. The man that my father was when we were Marylanders is totally different than the man he is now in southern California.
