I keep a bowl of sugar-free hard candies (chocolate caramel & toffee flavored are great) which I graze on . They sell these at walmart.
They are 8 calories each and take a while to consume. Sometimes I need 2 or 3 to quench the urge. It helps me to drink a glass of water in between candies. I get the sweet sensation, plus chocolate combined with the filling from the water.
Other ways I try to tame the binge is to eat raw baby carrots. They are sweet & crunchy.
Sugar-free popcicles also help me ---walmart has a big bag of these for about $2. They help treat the sweet tooth for about 15 calories per.
I wish I could say that these ALWAYS help control the binge monster in me. I've found that the thing that works best for me is to not have the foods I would really do damage with ----like cake, cookies, chips, etc.
