Okay, I really want to have something good tasty. I love iced coffee, but even sugar free kind at a chain restaurant/coffee places, raise my sugar.
I found Big Train - Blended Carmel Latte at my low carb store. It has 20g carbs, 7g fiber, 9g sugar alcohol (erythritol). Their label claims 4g of net carbs. I would probably count 13g net carbs. Do you also subtract sugar alcohol? I've never done that!
BUT, I did try their Vanilla latte, and I counted what their label said, 2g carbs. and I bolused correctly for it, since I didn't go high after that meal.
I LOVED their vanilla!
