Thanks for writing your query.
After reading your post, I would suggest that you should take an antacid
40 mg once a day before meals along with Domperidone
Keep yourself hydrated.
You should also get your blood pressure and pulse rate monitored.Dizziness
can occur due to low blood pressure. So eat a healthy diet prepared under hygienic conditions and drink lots of pure water daily.
If the problem persists, get yourself clinically examined and investigated.
I hope this is helpful to you.
