Im just like that. Had to get to wake up at 6 am to get to uni. Couldn't even eat until 11 without getting extreme bowel cramps that would get me "throne bound".

I can't focus well before 10-11 am whether I am working or not. It's like you woke a regular person up at 2-4 and told them to get dressed, eat something and go to work.

I did it though. Consistently for months in a row for uni or work. Constantly reacting weird to stuff because smh my feelings were always imbalanced, constantly feeling hazy. Every time, without fail, when the summer break came, as soon as I didn't have to force my body awake at 6, it would default to going to bed at 4 am and waking up at 12-13. I'd suddenly have infinite patience, stable emotions, focus like a machine! I was genuinely another person.

Fast forward to now where I can distribute my workload however I please and suddenly I not only work faster and more accurate, but more hours. Had I stayed at a "get up at 6" job, I'd have been called a lazy absent-minded uninvolved guy my whole life. Now I am easily top 5 most reliable in my office and people appreciate it.
