I tried the Pure Via in my coffee for several days. I usually use Splenda in my coffee. I had a hard time getting the right amount of Pure Via for the right level of sweetness that I like. I have tried another stevia product before and had the same problem. I also noticed and after taste with Pure Via just as I had with the other stevia based product. Even though product claims zero carolies per tube it does have 2 carbo's. This concerns me somewhat. I will use the rest of the Pure Via but I don't think that I will change from what had been using.
