It sort of started around 5-6 years ago. I just gradually stayed up later and later until seeing he dawn was normal for me before I went to sleep. Now it's progressed to being awake for usually like 36 hours at LEAST. that is my honest opinion. I don't know what to make of it though. The doctor ordered me to just buy sleep aids tablets. Sod that. I don't take unnecessary meds cos hardly anyone knows what they put in their and their child's mouths. That spreads though daily consumable items too.

Anyway, yeah I just sort of conditioned my body I think to handle more hours through the course of my school years.
Doing all nighters then going to school was a normal thing
