The last few months, my nights had been turning into such a true burning hell that I now have to take a strong muscle relaxant every night that puts me out and allows me to sleep for 6-8 hours. I literally was burning up from nerve pain, feeling restless and uncomfortable in my own skin, aching all over, muscle spasms, headaches.... I also think that the fact that it was dark, no movement/noise around = thus no distraction did not help the situation either.
Like you, during the day, no matter how bad my pain might be, I can find some sort of distraction. The pain does not go away, but it allows my brain some breathing space as it were. Just looking outside and observing birds, for example can help. (I have learned to adore birds. They are such gorgeous beings! How they take flight is fascinating.)
During the day, probably thanks to tramadol+paracetamol, I feel my best between 2-4pm.
