Could not fall asleep last night for some unknown reason -- maybe too much coffee and the blue light of my phone. Hours and hours passed by, and still more hours, but I was still awake. It means that I am very tired now, because I woke up at the same time as yesterday, only a little later. The plus side is of course that I can skip all duties today with a good conscience.

And another plus side: usually I sleep well these days. I have learned to live with my sleep disorder.

I have not had anything sensible to say for some time. Maybe I will find something later that inspires me to say something more substantial.
