Need Support

I need some advice/support. My husband has finally lost patience with me. In fairness to him, I have been trying to work this program since 2008. I can never get past step 2. I end up giving up the journaling, starting step 3, failing it, and quitting the program, only to start it all over again a few months later. My mood swings seem to be worse and worse. After my latest "blow up" my husband told me that he doesn't want to hear about my "sugar diet" anymore. He's can't continue to get his hopes up only to have me binge again. He said he's going to start "calling me out" when he sees me eating sugar. He is absolutely right to be so frustrated. But, here's my dilemma. I would like to give up the sugar cold turkey, but I know if I do that it won't last. But, when I start step 3 he will see me eat sugar with every meal. Does anyone else have this issue? Any advice?
