I have to agree with Shannonsnail- I love sugar, and have never really been able to do it in moderation. I have to go cold turkey to get off of it. Then after a few weeks, I am able to eat small amts of dark chocolate (80-90 percent) only.
I stop craving sugar when I don't eat it. If I start eating it again, I start craving it all the time.
I don't care for, or use, sugar substitutes though some people use them.
I would recommend going cold turkey- no sugar. It's hard for a few days, but then it's fine
When you do have sugar for a special occasion after that, you don't overdo it bc it tastes REALLY sweet!
