The purpose of this study is to evaluate response to non-erosive reflux disease (NERD) treatment between patients with normal endomicroscopy findings compared with patients with abnormal endomicroscopy findings. The researchers will compare two different drug regimens for the NERD subjects to evaluate their effectiveness in reducing NERD-related symptoms. In addition, the researchers will be testing the function and effectiveness of the confocal endomicroscopy procedure to be used during the study. Researchers will be continuing to assess the status, symptoms, and any changes associated with the symptoms subjects are experiencing.
