In May, my dental hygenist said I have an extremely dry mouth. Now, in September, it is waking me with burning in my mouth. I am getting up and melting chipped ice in my mouth for comfort. Also, I have now come up with an extreme diarhea 4 to 5 times in 30 minutes with heavy stools. So far, Immodium will stop it. But it occurred again after 2 days. What should I do?
