I agree that at first, you'll probably do best if you get the foods out of the house. The other people in your home can go out for their sugar or flour fix, if they want. If you do the cooking, you get to decide what to buy and prepare. Put yourself first in this. Others will adjust.

I've found it helpful to quit using "should" and "must" and "Got to," even when I'm just thinking. Instead, I've replaced those sorts of terms with more self-loving and positive ways of thinking: I choose to eat healthily. I would like to avoid sugar and flour. I deserve to be healthy and free of binge behaviors. I enjoy my morning walk. It's must easier to realize what I want to do and then do it; shaking my finger at myself and "shoulding" myself half to death just makes me want to rebel!
