I FEEL AMAZING.
Getting 8 hours of sleep is not a joke, it really has changed my life. I'm waking up happier, I have WAY more energy which means I have been exercising more, I haven't been as hungry for carbs and things (so I've lost a few pounds) and my house is really clean.
I was very skeptical of how a single, working mom could go to bed so early and still get things done and have any time to relax. But for some reason, my extra energy during the day is helping me stay on top of cleaning, so that there's not a lot to do after the kids go to bed, just about 30 min of picking up, doing dishes, etc (during which time I talk on the phone to catch up with friends). Then it's only about 8 pm, and I get some reading material, get ready for bed, and watch tv or read until I go to sleep. It is really rather amazing.
I was going to do it for a week... but now I think I might extend it indefinitely!
