Thanks for your question.
Sorry to hear about your illness.
It seems as if you are having GERD. Good response to omeprazole also makes it likely.
Make sure that you are taking atleast 40mg omeprazole daily.
You can add Tab Domperidone thrice daily to help this issue. Its a pro kinetic drug.
Avoid alcohol, tobacco, smoking, spicy foods etc.
See a gastroenterologist if symptoms doesnot resolve or worsen.
