I'm having gastritis issue for past 3 weeks. I'm feeling discomfort in the chest area, belching all day, feeling weak and energy less. Feel like eating every half an hr to overcome the discomfort. It has become more for past 4 days. I took Rabeprazole 20 mg for first 4 days. It didn't help for long time. Started taking pan 40 twice a day for last 3 days. I'm feeling a little better but not completely. Feeling stressed too and it feels like it's increasing the gastritis issue. I keep drinking warm water. I don't eat junk, oily or spicy food n I stopped taking coffee/tea since 2 months. Can I continue the same pan 40, if yes, for how many days. Please help.
