Yeah.. I asked my OB about it last time, and he said while it's true that it can cut off blood supply to bub/legs or whatever.. he said you'll feel sick and will instictivley change position anyway before anything dangerous happens.

I would doubt any pg woman would be taking sleeping pills or drinking alcohol, putting them into an unnatural sleep where you wouldnt' wake if it was uncomfortable.

I find myself still sleeping on my back. I wouldnt' worry too much about it yet. But as you get bigger, definitely invest in some pillows! hehe. I had to have one under my belly when on my side.. it felt like it was pulling otherwise.
