Actually, I'm not sure that it is insomnia. Once I fall asleep I'm mostly okay but last night it took over three hours for me to doze off.
As I was in my own room, I passed the time in a strangely productive manner. First of all, I made stitch & row markers for a maternal Christmas present. That's not the strange bit.
I have a compartmentalised case in which I keep my beads, buttons & other bits and bobs. I decided that the bits and bobs were taking up vital bead room so I moved them to one of those white embroidery thread boxes. Then I noticed that there were googly eyes mixed up with rhinestones, so picked them out. To cut a long story short, I ended up sorting several hundred rhinestones by shape, then several dozen googly eyes into round & oval. Dave laughed at me, because I make fun of him reading his comics in alphabetical order. I don't care, it will be easier to find the right rhinestone when I start making my Christmas cards and it was very soothing activity which helped me relax enough to fall asleep.
I'm not anal, I just prefer things to be arranged. Nothing wrong in that. Now I've arranged one medium sized box, I can move on to the entire rest of my flat. Yes, sirree, that's what I'm going to do. Dave will also have to be properly instructed in the correct arrangement of everything.
But only if I never fall asleep again.
