I asked the same question on the debate forum, trying to get both sides. I still have the question, will it work if I don't add the citric acid . I think that that is what scares me. If I added the drops to distilled water, would it still help me. Since I am dealing with problem with my lungs, this is what has stopped me from trying it yet. I am not afraid of getting a little diarrhea, I just don't want to make my lungs worse. So will it work unactivated?
