I'm hunting for hidden calories in my diet and discovered that the sugar-free drink mix I currently drink isn't calorie-free by any stretch. So now I'm looking for a replacement. I've found one or two mixes online that say they're calorie-free, but I don't see them as a product sold locally in Wal-Mart or Publix (my two main supermarkets). Does anyone have a recommendation? I'm not looking for a tea mix or a specialty item that's going to be prohibitively expensive. I'm not a big water-drinker, so I'm not going to drink nothing but water, so please no recommendations that I do.
