I have a weird GI situation. I do not have heartburn. I bark/cough routinely throughout day & night. Cough produces large amounts of clear fluid. I have to sleep sitting up. My stomach gets nauseous at the drop of a hat and when I throw up, I often dry heave even if there is food in my stomach. Had an endoscopy. Diagnosed gastroparesis but meds don't touch this issue. Anybody else?
