Acid reflex is one of those disorders that can just drive you up a wall trying to figure out what to eat, what not to eat and what on earth can be done.
I've heard that slicing a red or yellow delicious apple into sections and munching on it through the day can help relieve acid reflex. Dripping a little honey on the sections can also help. Just make sure you buy your honey from local bee keepers or at least make sure it's from the U.S.
