Yes, in another way
I am not sure if I am sleeping more or less, but I think I am sleeping better. I am certainly paying more attention to how well I sleep and feel I am able to improve it.
It confirmed my sense that if I sleep long one night I am apt to sleep for a shorter period the next. My sleep pattern is wavy, not straight. What I never considered before was the efficiency of my sleep, and I seem to do better on that measure than I was aware of.
If I wake up during the night and have difficulty getting back to sleep I try harder to employ techniques that I have learned will help me clear my mind and get back to sleep. I am less likely to give in to being awake. I guess I have also learned that I do have some control over the efficiency of my sleep.
