I had to have 1 cc taken out due to stacking. I coughed for 4 months and my family doctor thought it was my lungs. She was wrong. Then I had a EGD done and they told me my esophagus was messed up. Went to my band doctor, learned about stacking and I got a 1 cc taken out and the coughing stopped and no more choking feeling. I have gained 10 pounds in 6 months. I'm scared. I want to be refilled.
