Do you function best in the morning, afternoon, or evening? Explain

I think I function best during the afternoon. Im sure it is clear when I sit in the back of the room with my blank stare some mornings that I am not the most chipper person in the morning. Sometimes I can be but not usually. At night I am so wiped out from the day that I just want to go to sleep. Making the afternoon the point that im most alive. I can actually think and be active.
