Thanks for writing your query.
After reading your post, I would like to advise that you can take an antacid
40mg once a day before meals along with Domperidone
30mg after consulting his doctor.
Following precautions will be helpful :-
1.Avoid spicy and oily foods.
2.Avoid being empty stomach for long periods.
and alcohol, if any.
4.Drink lots of water daily.
I hope this is helpful to you.
