No, really. I haven't gone 'round the bend.
My shoulder, arm, and wrist have been fairly fucked up for several months now, and recently my neck has joined the fray. Whee. I realized a few weeks ago that sleeping on my right side, which happens to be my natural sleeping position, significantly exacerbates the problem. My left side is better, but on my back is best of all. The problem is that sleeping on my back is difficult for me. I've started being able to do it, and sometimes it helps more than others.
If I go to sleep on my back and wake up on my back, I spent the night on my back, right? Damned fine question. How to prove it? Enter technology. In this case, a laptop with an integrated webcam, and software set up to capture an image once ever 30 seconds. This morning, I took the thousand or so jpegs, turned them into a movie, and watched myself sleep. It's fascinating and creepy.
Sooo... if I go to sleep on my back and wake up on my back, I spent the night on my back, right? Nope. I think I spent about a third of the night on my left side, but it doesn't seem like I rolled onto my right side at all. That's consistent with the fact that I don't feel too bad this morning. I'll repeat the experiment a couple more times I guess-- it's interesting information to have.
And no, you can't watch.
