Oddly, I behave really well at the grocery and buy plenty of good things and few bad things, usually I buy only very good things.
This is an interesting idea. I was talking with my coworker who is also a junk food junkie. He was talking about how his boss in his department got gastric bypass. He is still out of work and recovering. My coworker, "Sam," said: "If you can't do things yourself you have to outsource the discipline. And that is what gastric bypass does. So I will probably have to do it in a few years or so too."
Ideally I would like to cultivate a strength from within that overcomes this addiction.
And to be realistic: When I am on a rampage a handful of locks and maxims will not stop me, not even close. On a binge I am a total, wild-eyed maniac.
