Are You Trying to Change Your Sleep?

i've noticed that a overtime, i probably have not felt as refreshed when i got up in the morning. In some cases, i've been waking up several times i the middle of the night. And i was curious whether this was a pattern, or whether it was actually affecting my sleep, or whether i'm just imagining it. My concern is you still have to be able to measure the input, right? You got to figure out what is it you did on each day as a result of that.
