I think sugar is a clinical addiction complete with cravings while detoxing, and lifelong cravings. A recovering alcholic or former cigarette smoker will still get cravings, sometimes very strong cravings, years and years later. The idea that you wouldn't be craving sugar 4 days out to me is laughable. You'd expect to be going through cravings like crazy if you were trying to get off alcohol, nicotine, heroine, or any other addictive drug. Society aknowledges that the cravings are so strong (and the side affects from coming off it) that many people don't try to quit or get sober, PARTICULARLY with nicotine, since it is socially acceptable. Well sugar is a socially advocated drug, and even more prevalent. Take it easy on yourself, and keep trying. Going off refined sugar is very difficult, and SO worth it. (I also personally beleive it is impossible with things like cookies in the house.)
I'm personally debating whether I can eat sugar occasionally (like I want to) or if I need to go cold turkey on refined sugar, and declare it to myself an allergy, that I can't digest. I'm not sure. I think I should go completely off sugar because I feel so crappy after eating it, and I have so many problems that are extremely exacerbated by refined sugar, but.... who wants to go off sugar to the extent that they can't have birthday cake or pie that others made with white sugar? Its really hard to do.
