sugar fast, revisited

First read this. Now we can talk. It has been 5 weeks since I have quit sugar. I decided to continue the fast an extra week because it was working so well. So my question right now, as I contemplate a post-gym biscotti for a small treat sometime this week is, How good is too good? I suppose, since the sugar fast is bringing me my desired results, that I should continue my fast. But I am more in favor of moderation than cold turkey. Intellectually speaking, that is. In practice, I am better off with cold turkey. I don't know. Feel free to chime in about your own New Year's resolutions here.
