hernia surgery 10 years ago, it worked great , and 1 year ago my symptoms returned hard, look for alkaline diets on google,give it a try for a week eating 70% alkaline foods and 30% acid, i was suffering for extreme acid reflux, i changed my diet and stop using 40 gram nexium , i am out of nexium now and feel better than ever, no bloating, no reflux and my throat feels like singing!!! i hope it works for you!
