A long time ago I went 6 months without sugar. The cravings did subside, but I didn't lose weight (I ended up eating bread with butter and chips and such).

I almost never have sweets in the house. I go to the nearby 7-11 or the new bakery in town (cupcakes-so good!). Sometimes I make cinnamon and sugar toast. Oh and I do buy ice cream, which didn't use to be a problem (I could eat just a small amount), but now it's become an issue.
