I use to get heart burn a lot - would take Tums for awhile then would take Nexium for a couple days - that would stop the heart burn for awhile but eventually it would come back - I watched this doctor on the net and listened to what he had to say - the problem is not too much acid in your stomach but just the opposite - not enough acid - so I started drinking some apple cider vinegar in water - 1 tsp in a glass of water each morning and then a little during the day - also I don't drink anything while I eat so not to dilute the acid in my stomach - it works - believe me haven't had any heart burn since -
