When you talk about the terrible pain in your chest I can relate to that --but mine is felt in the back--it's my oesophagus I know, as yours will be.When you talk about weakness that describes exactly how I feel.I do believe that cutting grain carbs helps(bread etc) I have found apples to be helpful for me, contrary to what Dr Norm says. I also believe that plain yogurt containing the good bacteria also helps especially if I take it at breakfast time. I have been cutting carbs for a few days now and I am feeling so much better.All the pain has gone from my back and I am more positive...I am controlling it rather than it controlling me. Eating a lot of vegetables, salads and protein along with plain yogurt and a little fruit for breakfast has helped me a lot.
Everyone is different but cutting carbs seems to help reflux.Good luck!
