Talk to Gastroenterologist on Stomach Ulcer

I'm a patient of stomach ulcer. it's been more than 10 days and I feel it's still not gone. I started medicines 8 days ago. My doctor prescribed me omeprazole (2 times a day before meal) and Metrozine (2 times a day after meal). During this period I had side effects of omeprazole i believe as I felt dizzy mostly and had some abdominal pain as well sometimes, my stool got well and turned even in better color as it was dark brown before. I've been on only vedge, chicken and lentils diet since last 4 days and I've also started taking cabbage+apple juice everyday (as I read that its very beneficial for stomachs ulcers). Now my medications are finished and again I'm having loose stool with dark brown color, Im still eating less oily(only olive oil, little salt diet everyday but still feeling that ulcer is there. Also please recommend any foods that I should eat, I'm eating lots of veggies and haven't eaten meat since last 15 days, eating only boiled chicken and having roti. Any supplements
