Hence Iw ould advise you the following:
Since you are staying in a hostel you need to make a list of foods and beverages that suit your stomach and intestines and does not cause any problem. Continue with these.
Also make a list of foods, beverages and factors that caused you the problems and stop these altogether.
Also take an antacid and a PPI like

If these do not help it is better to go for the follwoing tests.
