hi there, you seem to be suffering from reflux esophagitis
and for that you need to continue taking an antacid
and sphincter tightening tablets. Zintac is also an antibiotic but something like pantop or Nexpro
would be more benificial. You could also take perinorm
to decrease the reflux. Also mild change in your present life style would help.
If you drink or smoke then you have to cut down on them if not totally stop it
You need to take your meals at regular intervals preferabley low in fat and spices and in small quantities
keep a gap of atleast 1 hr between meals and bedtime and try to take a stroll after supper.
Hope these help you. Take care.
