Too little sleep

I stayed way too long at Anna's yesterday, Maja and I weren't home until midnight. Then she didn't go to sleep until one and for some weird reason I couldn't fall asleep. Hopefully I was asleep at 1.30, but I don't know. She woke at 3.30 to eat and again at 7 and then I just couldn't fall asleep again. Partly due to pain and partly due to the garbage compressor, but now it is reasonably quiet and I have taken some paracetamol and I still can't sleep.
Tonight my brother-in-law (to be, at least) is coming over to play DBM with my husband and my sister will join us after she's had her last test at her engineer's education. I'm going to ask her to help me dye my hair because last time I missed some hair so the colouring isn't even. It's tricky to get dye everywhere if you have a lot of hair.
