I've found that my sugar cravings go away almost immediately when I keep refined sugar out of my diet. The effects of eating ANYTHING, even one piece of candy, with high fructose corn syrup hit me right away. It was one of my most exciting discoveries at work.
Ok, I'm a nerd, but I realized that I was ravenous when I'd have candy at work but fine if I didn't. I've even got the men in my life paying attention to their sugar and they agree.
So... I agree that after a few more days you should be feeling fine, but also keep an eye out for the kinds of sweeteners/sugars in all your foods to see if any of those are triggering your sugar cravings.
