I suffer from chronic gastritis and non-dyspepsia ulcer and acid reflux. I've been on Nexium for over a year now and it just doesn't seem to be working anymore. I've had two endoscopies and the results have been the same. I do have a hiatal hernia and don't really know how much that plays a part of my indigestion. I recently read where I could add another acid blocker to my regimen. Just wonder if anybody else has any suggestions or help that they may give me .
