I have been plagued with diarrhea for years now, I have completely cut out all sugar for about 2 years now and that helps a lot. I have notice recently that when I have lime juice it firms me right up, even better than taking anti diarrhea pills. Why do you suppose that is? Could it be PH related? I know that my system is pretty alkaline, has been every time I checked it. The doctors I've talked to about this are no help, now I don't have insurance, I live on a small island in Hawaii. I am 58 years old, super fit in every other way, I cycle long distances, ride horses, grow a lots of the food that I eat too.
