I have had gallbladder surgery and the Nissan. And 20 plus years later I am suffering from choking, the sensation of food being stuck, and severe heartburn. I take 2 medications at night, yet still wake up and have to take Rolaids. How long can a person take these meds before nothing works. I have even used the cocktail lidiocain with maloox . I am lactose intolerent which causes multiple GI problems.. Any suggestions.
