Does brain work better am or pm?

My brain definitely is more active at night and always has been. I don’t know why but perhaps because during the days I get more anxious, whereas at night I am more alone with my thoughts. It’s very frustrating anyway and especially if I’m feeling depressed. Then that tends to become dangerous, depending on how severe it is.

I used to consider myself a morning person. One of my first jobs was as a breakfast chef. I used to have to get up a 4am, cycle 10 miles to work, to start at 5:30am.

Now though, I still wake up early, but it's motivation I struggle with. If I have nothing planned it'll take me hours to get going, but if I have planned something I'm usually up and on it.

For me, it's the most peaceful time of the day/night because most humans are either still asleep or have gone to sleep. 

Blimey, I couldn't even think about studying 2200-0100

Could be a bit of an age thing

In my case, it's hit and miss regardless of the time of day! I would say that my best time for any kind of study is either very early morning (before 07:00am) or late evening (22:00 - 01:00am).
