I'm up in the middle of the night often too and I know how those hunger pangs and blood sugar swings can go. I just drink some water and grit it out. Are you knitting, watching TV or writing at night? I will start stuff after 4AM and just call it an early morning but will not generally do much more than some dishes in the middle of the night (you know the pot left to soak that you'd rather not face when trying to get the family out the door).
And yes, it is important to count our many blessings... I think it allows us to gratefully ask for what we need next to move along our path.
