The tools I'm using are working great. Exercise, 5HTP, South Beach. I've lost 9 pounds since sunday and haven't experienced anything even resembling a craving.
Sugardude,
Glad to hear you are continuing to make progress. I'm particularly interested in your results with 5-HTP. The science behind this is very interesting, and provides a good explanation for how 5-HTP can alleviate sugar cravings:
1. A deficiency of serotonin in the brain can cause endogenous depression and increased appetite, which is particularly directed towards sugar and other refined carbohydrates.
2. Sugar consumption stimulates the body to produce insulin, which transports glucose, fatty acids and amino acids (except tryptophan) into body cells. Thus insulin speeds up the absorption of amino acids other than tryptophan.
3. Normally, tryptophan must compete with other amino acids for entry into the brain, but once insulin eliminates the competition the level of tryptophan rises in the brain, where it is converted to 5-HTP and then serotonin. The result is an elevated mood and reduction in cravings.
By supplementing with 5-HTP you are boosting your serotonin levels by a more direct route, eliminating the need for sugar-->insulin-->tryptophan as a source of serotonin.
So there is at least indirect evidence that low endogenous serotonin levels may explain your vulnerability to sugar cravings. If that is true, it suggests also that anything you can do to boost serotonin levels naturally will help. One way is to eat tryptophan-rich foods such as lean pork, legumes, peanuts, soy, cottage cheese, milk, chicken and yogurt--probably all acceptable within your improved diet (South Beach). But in addition, regular exercise, over time should naturally restore your serotonin levels. Some of the evidence for this is referenced in this review article on non-drug approaches to raising serotonin (towards the end of the article):

Tryptophan-rich protein foods will short circuit that vicious circle. And exercise will re-tune the circuitry to eliminate the viscious circle.
