GERD
"I had bad, wheezy coughing and doctors thought it might be COPD. Then, on a hunch, my great doctor thought the coughing might be due to my GERD so she suggested Zantac150 twice a day.
 What a difference! I still need an inhaler, but my cough is otherwise gone...and it was REALLY bad for months (even with inhalers).
  Been on Zantac for about 2 weeks - no discernible side effects."
