Thanks for writing your query.
After reading your post, it seems that you should take an antacid
40 mg once daily before meals.
Following precautions will be helpful :-
1. Avoid spicy/oily foods.
2. Do not miss meal.
3. Avoid emotional/mental stress
4. Drink lot of pure water daily.
5. Avoid smoking/alcohol, if any.
If the problem persists get an Ultrasound
of abdomen done and get yourself clinically examined .
I hope this is helpful to you..
