Libby,

Many people have the same effect from eating Maltitol. You might want to check the following website, which has some good info about Maltitol and it's effects:

There is a GREAT chocolate bar called ZCarb bars that you can get at Wal-Mart and various other places. They use Inulin - which not only gives it the same taste as chocolate, but the same texture also!! They come in Milk Chocolate, Milk Chocolate with Almonds, Milk Chocolate with Peanut Butter, Dark Chocolate, Dark Chocolate with Soy Crisp, and Dark Chocolate with Macadamia Nuts. They haven't stalled me, my wife, or my son - and they have Zero net carbs and 158 Calories.
