Rested?

For the first time in months I woke up feeling rested. We put Evelyn down at 830 last night and she didn't wake up until about 3am or so. After a quick nursing, I was able to put her down without fuss and we woke up at 630 today. It was an unbelievably wonderful feeling I didn't even recognize. I woke up thinking "I feel different, what is it?"
