I cough, especially in the morning, until I almost vomit or do vomit.  I wake in the middle of the night coughing.  If I do work that entails bending, I cough and have to wait to continue until I stop and also catch my breath.  I feel like hot fumes are coming up.  I have been on Prilosec once a day, then twice a day; then switched to Dexilant then had Renatidine added.  Nothing works and nothing stops it.  I have also been given nasal sprays for post nasal drip which dries my throat and then I cough from that. I do have a small hiatal hernia.  My diaphragm is held up on one side from adhesions from a lobectomy.  Could this be holding the stomach valve open?  Is there anything else I can do or my doctor might do?
