I am on the Atkins type diet as well. Can have whatever I like as long as I am under 20g of carbs a day. I am on day 5 and am doing well. I had one day at 21g but the rest have been under 20g.
I agree they are not the greatest. I mix the margarita one with Sprite Zero and it is delicious!!! The new white cranberry cosmo is my new favorite, I drank that as is but also tried adding Sprite Zero and it stated yumm.
