Vomiting and burning sensation. Suggest.

From past 4 months, I am experiencing burning sensation just below the ribcage which aggravates right after a meal. Many a times the whole meal gets vomited out. Every morning I  vomit a clear acidic liquid that leaves my mouth sore. I went for endoscopy in Delhi and the doctor explained from endoscopy results that area connecting stomach and food pipe is weak by birth and due to the acidic vomits there are many cuts in the region which causes the burning sensation. I have followed the lifestyle changes suggested like not sleeping or drinking water right after a meal, avoiding citric and fizzy foods and am taking nexpro and Moza medicine from last 2.5 months. However, the moment I stop medication or have a little heavy meal (totally non acidic), the symptoms resurface as if there is no change at all. Specially when I am going through stressful times at work, the symptoms become very strong. Please suggest.
