I fall asleep really fast when lying on my back, but I find it uncomfortable so I rarely do it. I sleep on my side, whichever one feels "right". There's just a feeling when I get into bed that tells me what side I need to start on. Usually I lie on that side until I'm just about to fall asleep and then I roll over and sleep. And since I got my water pillow I actually sleep through the night, rolling over once in the morning to "even out" my body because it's feels wrong if I only sleep on one side and not the other at all because I used to toss and turn all night.
