erosive esophagitis
"With having discomfort for years after i had been to the doctors  and they weren't quite sure what was wrong with me and diagnosed me with ibs. After years of not getting better they decided to do a endoscopy and it showed I had esophagitis.  They started me of on 20mg for 2 weeks then increased to 40mg I must say I had no side effects and not one bellyache or chest pain or heartburn since I am overall happy with this drug."
