Hi ! Thank you for posting your question here . I would say that you hungry feeling may be cause of your acid stomach .The drug reduce the acid but not totally .The acid stay in the stomach dont go and makes you feel the symptoms .In this case I recommend to eat small meals often during the day . Food will help to empty the acid for the stomach ., Avoid food that irritate your stomach ( fatty food , caffeine , food that contain acid -fruit juice , no smoking , no alcohol .) . Another thing is that Razo can cause headache , ( it s a rare side effect of this drug ) . Follow the food advise to see the changes . Also you should check for H.Pylori infection which is the more often cause of gastritis , .If the test is positive your doctor will start the treatment against , add antibiotics. Wish these help . If you have any other questions please feel free to ask me .
