Thoughts are mainly about work and problems that I need to solve. When I am trying to sleep, I will sometimes work on a problem in my head because it's "bothering me", and this can postpone my sleep by up to an hour. This happened to me a lot in college on homework sets. Some sets would take hours to complete, and if I could not solve a problem before sleeping, I would "give up" and go to sleep, only to continue thinking about the problem. The best way to describe what is happening is: I'll be trying to sleep, and I will think about the problem statement. Sometimes I will find a new perspective, and follow that. If it doesn't lead anywhere, I will go back to the problem statement, and the process repeats. Sometimes I'll just repeat the problem statement in my head hundreds of times over the course of an hour, hoping I'll find a different path to the solution. It's tempting to keep thinking and not sleep. In my experience, this is an affliction more than it is an asset. This is why I am interested in L Theanine.
