I tend to sleep on my right side. I sometimes shift to the left side, but I find that sometimes during the night something or someone turns me back on my right side.

The reason I don't sleep on my back is I snore. I will wake myself up, curse, and turn on right side. I used to lay face down. I can't tell when or why it changed. Maybe the body know what it needs without having to think too much about it? :)
