Try a proton pump inhibitor
I am sorry to hear about your troubles. I suggest you try a proton pump inhibitor (e.g. pantoprazole 40mg x 2) for a few weeks. Also, try to avoid spicy and smoked foods, ibuprofen, smoking and alcohol. You should also avoid late meals, and sleep with your head rest elevated.
Let me know if that helps, and feel free to write again if you have further questions.
