Thanks for writing your query.
After reading your post, I would like to advise that you should get an ultrasound
of upper abdomen done.
Also get your blood tested for Liver Function Test(LFT) and serum amylase
I would suggest that you should follow certain precautions like :-
1. Avoid spicy and oily foods.
2. Avoid being empty stomach for long periods.
3. Avoid smoking and alcohol,if any.
4. Drink lots of water daily.
You can take Domperidone
30 mg along with omeprazole
Rest management can be planned after knowing the reports of the investigations mentioned above.
I hope this is helpful to you.
