Welcome to icliniq.com.
I read your query and understand your concern.
Your symptoms suggest it can be functional dyspepsia or irritable bowel syndrome.
I have these suggestions for you-
1. You must avoid eating spicy junk food and juices.
2. You must try to eat small frequent meals.
3. You must take low fat and low carbohydrate diet.
4. You must drink plenty of fluids and water.
You can continue your medication.
5. You can add a tablet Acotiamide (gastroprokinetics) 100 mg thrice a day.
