You have Re-listed the question; thats how i stepped in.
I have read your queries in detail.
At this point you should continue with 40mg daily omeprazole since your problem has not improved. Some times even higher doses (40mg twice daily) have to be given to control reflux and such symptoms.
In addition to the foods pointed out by the other expert, and domeperidone (has to be taken at least half hour before meals and if doesn't help its dose can be increased); you should also try Simethicone containing ant-acids --- which will greatly reduce the gas production and burping.
This seems to be gastritis, most likely due to combination of increased acid secretion from stomach, reflux as well as the drugs (antibiotics you took) and this may take few weeks to settle down.
And if after two weeks you do not feel any improvement in your symptoms, you would require an endoscopy; as well as tests for H.pylori (once again).
