Thanks for writing your query.
After reading your post, I would like to suggest that you should start an antacid
40 mg along with Domperidone
10 mg once a day before meals.
Following precautions will be helpful :-
1. Avoid spicy/oily foods.
2. Do not miss a meal.
3. Avoid emotional/mental stress
4. Avoid smoking/alcohol, if any.
5. Drink lot of pure water daily.
I hope this is helpful to you.
