A couple of interesting posts from Food Renegade:
On how L-glutamine supplements might help cravings for sweets:http://www.foodrenegade.com/how-beat-sugar-cravings-glutamine/
On using fermented foods to help sweet cravings: http://www.foodrenegade.com/zapping-sugar-cravings-with-fermented-food/
There are several more sugar-related posts from FoodRenegade, but a warning that the site is heavy on commercials.
Yours in exploring,
