A friend of mine sent this... she claims it works.... I don't know anything about agave syrup, which I highly suspect is a sugar too.....

1/4 teaspoon of cinnamon will get rid of sweets cravings.

To curb chocolate cravings and also sweets cravings in general, drink some sesame seed milk. To make sesame seed milk, soak sesame seeds in spring water for 1/2 day. Put the soaked seeds in a blender with twice as much spring water as seeds. Blend until fine. Strain out any solid flecks and the remaining liquid is sesame seed milk. Sesame seed milk will keep in the fridge for two or three days. To improve its flavor, add some drops of liquid stevia or some agave syrup and some vanilla or some cinnamon, all to taste.

I made some sesame seed milk and it seemed to do the trick. Its taste is so-so, but maybe I did not get the sweeting and flavorings quite right.
