I'm not a morning person either, although by afternoon I'm fully functional.
I recall when I was younger trying to adopt a "early bird gets the worm" routine. Went to sleep at 9 PM, woke up at 5 AM, drank a coffee, went out in the chill of the morning for a vigorous jog, came back into the apartment, drank another coffee ... then went back to bed and slept like a baby until around 9. Going back on the memory lane, school was a nightmare. With it's start at 8 AM and wake up at 6:30, I mostly spent it in a tormented fuzzy stupor.
Now I kinda accepted there's literally nothing I can do to wake up my brain "on the double". Thanks God for WFH, sleep till 9, start work at 10, I'm almost functional. By noon it's all engines running.
