I am a stomach sleeper and have been for as long as I can remember. In fact, if I sleep on my back, I get nightmares or really strange dreams. I use an orthopedic-type pillow and even put a pillow under my hips to keep my hips up so my back doesn't bend inwards and that reduces any back or neck pain and keeps me comfortable. Even so, I still wonder why it's often stated that sleeping on your stomach is not good to do.
