I've been having a hard time staying in bed in the morning, because of low level pain. It was one of the reasons for a new mattress and also for an adjustable bed. This morning I woke up at 4:30 and managed to stay in bed until a little after 5. At that point I used the adjustable bed to lift my head and my knees just a bit and tried to fall asleep again.
It worked. I didn't get up until 7:30. I'm pretty sure I've been generally sleep deprived for the last couple of years. I think 7:30 is a lot closer to when I should be getting up considering when I'm going to bed most nights.
