I am having my neet exam day after tomorrow and i am suffering from gastritis since march means frequently using antacid or ppi tablets sometimes daily for 1 or 2 days or sometimes weekly. The main issue is that I can't sit for more than 4 or 5 hours without food and on the day i have to sit for atleast 7 hours and it makes me extremely uncomfortable without food like pain type feeling starts in head and gas pain in various places of body that resolves on eating. Please suggest a way possible and if antacid is your preference then please mention that can i use aciloc 300 because normally i am using 150 since years. Will there be any side effects?
