I have acid reflux, without heartburn. The worst part for me is that I have a horrible taste in my mouth at all times. I have been on every ppi med. you can think of, nothing helps. I started to watch what I'm eating, trying to stay away from acidic foods. I don't want to talk to anyone to their face for I know this will be a disaster. I see people cover their nose and mouth when I talk and I 'm maybe 6 feet away. Does anyone have any ideas for this problem, my doctor said so calmly, just chew a piece of gum. If only it was that easy. I have tried everything.
