WJFInteresting question and I am wondering if you have been diagnosed with this disorder ?
From an article : http://www.gastroendonews.com/ViewArticle.aspx?d_id=187&a_id=16551
"The study investigators found that patients who were PPI-resistant and diagnosed with hypersensitive esophagus using 24-hour pH-impedance monitoring experienced reduced reflux symptoms after receiving 20 mg of the SSRI citalopram compared with a placebo."
