I used to cough four years ago, but stopped. Now, lots of mucous and pain in center of my upper GI. Try Gaviscon Plus from Amazon. It coats your esophagus and hopefully acid will not damage it. Baking soda and warm water and salt water do magic too. I rinse my nose with salt and warm water and gergle with it as well. I also gurgle and brush my tongue and mouth with baking soda and warm water. If you can Tagamet, take it and see if helps. Tagamet helped me but got Sibo had to stop. After eating, don't bend over. The cough is the result of acid. Diet is the best solution. Google and find out what you should not drink or eat.
