Gastric issue. Continue that medicine?

Hello doctor! I'm having gastric problem for past few months. Usually will be having lunch by 12:30 pm to 1pm and after that dinner by 9.30 pm. I'm getting acidity, heartburn, also gastric hiccups by evening time sometimes continued until having dinner. Sometimes acidity reflux also happens. Once I have consulted doctor and he prescribed me "Nexpro L" everyday morning before breakfast. While having that I was free from acidity especially heartburn. Now when I discontinued it again the problem started. Can you pls advice me what is the issue is and should I have to continue that medicine? Sometimes I also take reflux forte syrup which give me temporary relief from heartburn and acidity. Pls advice doctor.
