Wish granted!

If I lie on my side for more than a minute or two, my hips ache. Only a little at first, but if I ignore it and fall asleep, I will wake up in writhing agony 30 minutes later. Been like this since my 20's. Reasonably healthy otherwise so I don't know what the deal is. Otherwise, yes, this would be the ideal reading position.

Extra credit: I can only FALL asleep on my stomach, but I can only CONTINUE sleeping on my back. Which means almost every night, I somehow flip myself over without waking up.
