I actually slept really well last night. For the first time in a very long time. I woke up feeling refreshed for once and I'm not really sure why there was a difference. I slept in the spare room last night, which faces out into the street instead of the back room where there's a huge garden behind me and a blackout blind covering the wndow.
I would think that it might have been waking up with the dawn that helped, but since I was awake a good hour before dawn broke I don't think that can be it.
Ah well, off to ponder the mysteries of my first good night's sleep for months, if not years.
