Just to pick up a point in an early post...
Josie said that as a rule if she wakes up tired in the morning she knows that she hasn't had enough sleep.
I worked it from the other spectrum...if I went to bed at a reasonable time - dog tired from my exercises I was guaranteed to sleep the sleep of angels and have a good calorie burn for the next morning (specially if I went to bed feeling a little bit hunger as well).
