Thanks for writing your query.
It will be helpful if you give information about any medicines you are taking for your symptoms.
After reading your post, I would advise that you should take an antacid like Omeprazole
40 mg once a day before meals along with Domperidone
30 mg for relief from your symptoms.Dicyclomine
can be taken for abdominal pain
You should take light meals prepared under hygienic conditions.
Also maintain your hydration.
I would also advise that you should get yourself clinically examined and investigated.
I hope this is helpful to you.
