like clockwork

Starting at around 3:30 every morning (sometimes earlier) I start flipping. I wake up and turn on my right side. An hour later I wake up and turn on my left side. An hour later I end up on my back. None of these positions are comfortable. I used to get some relief sleeping on my back, but even that's gone. I've tried sleeping with a pillow between my legs and all the other recommendations, but nothing works. I feel bad because I know I am keeping Tim up. He's such a light sleeper anyway. A big ole whale flopping from side to side in bed next to him can't help. It's no wonder we're asleep by 9:30 most nights.
