Natural Cures for GERD

I have chronic gerd and also am allergic to iodine. I use digest advantage for lactose intolerance an OTC in small amounts whenever my stomach acts up. I also take benadryl in very small amounts an hour or so after the digest advantage. It works miracles for me. I tried so many other meds that only worked temporarily and caused soo many discomforts. I am back to eating and drinking whatever I wish mostly.
