Hi Lynne,
No, it's not revolutionary at all! I was the same. In the early weeks, I slept a great deal but would wake at all sorts of odd hours unable to sleep. I got to the stage before I went back to work that I didn't need a sleep during the day. When I returned to work I always slept for a couple of hours when I got home and believe me, I needed it! Since then, I don't sleep during the day during the working week, and I have no trouble getting to sleep, but I often wake in the small hours and unable to get back to sleep again. Come the weekend, I'm shattered and almost always need a sleep during the day and often fall asleep in front of the TV. I'm a snorer too, much to the disgust of the rest of the family
Just lately, I've become a night owl, but that has very different reasons
All I can suggest is to do something that will help your brain to shut down at night. Take a walk before bed, for example. I've often found that a few beers usually help, but that's not the answer either
