I get this sometimes but I mainly get it when I want to work on my art, I think people like us are destined to suffer bouts of insomnia until we get our work done

there are times as well when I'm working on the story in my head and such where I just have to stay up to finish it because my brain is so active I won't be able to sleep anyway.
This is just a symptom of enjoying the work you do I suspect I don't hear about office workers and the like suffering from these kind of problems
