I guess I'm pretty lucky that I usually sleep very well. So I don't often wake up in the middle of the night for anything. I tend to do the whole poking-at-my-tummy and looking-at-my-hip-bone routine before I go to sleep though, and run to the scale in the morning. I do have binge nightmares though, and I'll wake up in the middle of the night from those... those really are scary!
