I too use Foundation care and also get my Hypersal free with my Colistin order...otherwise, it wouldn't be covered by my insurance. I also get free CF source vitamins..I have to say, they have been awesome! I strongly recommend that you look into them for your Hypersal, especially if you are on Tobi or Colistin.
