I'm up, after a mostly good night's sleep. I did wake up twice and the second time I finally figured out why. Yesterday morning it was around sixty-five in the house when I awoke, so I turned on the heat. I then forgot I turned on the heat so I never turned it off. I don't sleep well when the heat is on, and that was the problem. The second time I realized I was hearing the heater, so I got up and turned it off.
