Thanks for writing your query.
After reading your post, I would like to advise that you should add Domperidone
30mg along with prilosec.
along with digestive enzyme

2.Avoid being empty stomach for long periods.
3.Avoid smoking and alcohol, if any.
4.Avoid gas producing foods like peas, cabbage, legumes, etc.
5.Drink lots of water daily.
