In the past year there was a study released connecting sleep problems with weight gain. That made sense to me. Although I have had an issue most of my life, I became a confirmed non-sleeper at the same time I started to put on weight. Of course my love of all things delicious doesn't help, either.
I am not a night prowler though. I have learned to manage my insomnia to my best advantage. I stay in bed, I don't watch the clock, nor toss and turn. I have learned to lay quietly and rest. I know how to quiet my mind and simply be still. I believe rest is beneficial, so even if I don't sleep all night I am restful. I do sleep, just not the whole night, I'm a 2:00 AM waker.
So, now with all kinds of issues in the world that legitimately cause sleeplessness, I guess I have a head start.
