Thanks for writing your query.
After reading your post, it seems that you are having pain due to increased acidity in the stomach.
You can take antacid
40 mg along with Domperidone
10 mg before meals once a day. Antacid in gel form will also be beneficial.
Following precautions will be helpful :-
1. Avoid spicy/oily foods.
2. Do not miss a meal.
3. Avoid mental/emotional stress.
4. Avoid smoking/alcohol, if any.
5. Drink at least 8-10 glasses of pure water daily.
6. Eating Yogurt is good.
