Hey Yoda. I am a yoyo dieter/eater so I have been there done that on many occassions. It is very painful for me when it happens......... yet again. It is so hard once it spirals out.
I am fortunate in a way because I live alone. I have no children etc. While this may not seem fortunate, in one instance it is. I can completely regulate what comes into the house.

Although you are fortunate to have a son
