Most of the sugar free gum I have come across have only 1 carb - the serving size says 2 pieces. I only chew 1 piece at a time so 1 carb.

Most are also made with sugar alcohols so you can subtract the carbs if you want. (I always count 1 carb per piece). check your package, I haven't come across any made with Splenda yet.

I have stopped chewing so much - my jaw hurts!!!
