Are you temperate all day or is there a certain time of day when you're most upbeat positive hopeful?

I'm an early bird so my upbeat occurs when I wake up and stays that way until mid-late afternoon and then darkness creeps in. Perhaps due to the news of the day. Perhaps due to winding down. Perhaps due to the way I'm wired. What about you? When are you the downest and when are you the opposite? Does it occur daily?
