Locke that's great that you came up with your own. Use what works.
I use the scale given to me by my nutritional therapist. I believe it's the one from the IE book.
1. Famished, Irritable
2. Very hungry
4. Slight hunger
6. Appetite goes away
9. Overly full, stuffed
10. Sick, discomfort
I eat when I'm at a 2-3 and eat all the way to an 8.
"Binging is a descent into a world where every restriction... is cut loose. At its core is a feeling of deprivation.. a feeling you can never get enough. Binges do not signify a lack of willpower or inability to care for yourself. On the contrary, binges are a urgent attempt to care for yourself when you feel uncared for. They are the voice of survival. Binges are the mark of the self that says, 'I am tired of feeling deprived, of being told I am wrong, that I am bad." - Geneen Roth
