I’ve always been nocturnal from the time I was a toddler. Over the years I worked both night shift/day shift at different times and ALWAYS was more productive/creative at 3 am rather than 3 pm. I really don’t get tired until the sun rises. Then I sleep erratically for the rest of the ‘night’.
Sounds weird, bit for me that’s ‘normal’. Or I’m a vampire and just haven’t realized it yet.
