My entire life, I've been a night owl. I'm prone to depression in the mornings. I prefer to avoid doing anthing in the AM. In the evenings, I can have a lot of get-up-and-go energy and can be positive about a lot of ideas, but when I wake up the next morning, my entire mood has shifted and I'm often quite negative. Staying up all night (or only getting a few hours of sleep) avoids that mental reset that causes my entire mood to shift. I wonder if this is related to the phenomenon studied.
