There is a Blue Bunny Carb Freedom yogurt sweetened with Sucralose---6oz container has 90 calories, 5 grams carbs, 5 grams sugar 3 grams fat. I got the vanilla creme and added frozen berries. There are other flavors. It was delicious. I bought it at Super Target for 52 cents. Is this permissible on Sugarbusters? I saw Dannon sweetened with Aspartame listed in the Sugarbusters book but couldn't find it locally.
