Hi JoAnn, and welcome to LCing! Your post made me vaguely remember how I felt at the beginning, when all I did at first, for a month, was quit sugar and white flour. I was fixated on that thought, "oh my gods, you mean I'm never going to have a cake/cookie/fudge ever every again?" I smile fondly at this old self now. What has happened is that yes, I have lapsed and had sugar and flour again, but it made me feel so awful, now I want to stay away from it entirely!
Looking back on myself then, I see clearly that my relationship to sugar was that of an addict to a drug. The panic about giving it up forever was, for me, part of the addictive mindset. And so there is nothing for it but to do what the 12-steppers say: one day at a time. At first, that's all we can do. In a year or two, when the excess weight is gone, maybe you'll decide to have sugar occasionally. For me, the rule is to never bring it into the house--if I want a monthly indulgence (and monthly is about all I can afford), I go out and get a single serving of it, eat it in public. No more sneak eating or gorging on my drug.
I predict that once the carbs are out of your system, obsessive thoughts about getting more will ease with each passing week--at least that happens for most of us. I can't tell you how wonderful this is! We stop "living to eat" and instead we "eat to live," sometimes even forgetting a meal! The more you think, "that'd never be me," the more strongly I predict it will be you! The nature of hyperinsulemia.
Best of luck, and keep posting.
