Thanks for writing your query.
After reading your post, it seems that you are having increased acidity and gas production in your stomach, which can be caused by stress.
You should follow some precautions like :-
1. Avoid spicy/oily foods.
2. Donot miss a meal.
3. Avoid emotional/mental stress.
4. Avoid cigarette/alcohol, if any.
5. Drink atleast 8-10 glasses of pure water daily.
6. Avoid any self medication
especially with pain killers.
7. Doing yoga and meditation
will help to deal stress in a positive way.
You can take antacid
20 mg once a day along with Domperidone
If the problem persists, get yourself examined clinically.
I hope this is helpful to you.
