This is. Dr. David
it sounds like your stomach is producing too much stomach acid.
too much stomach acid and reflux will cause burping and gas and sometimes diarrhea.
it sounds like you have GERDs
you may have to avoid foods which worsen your stomach acid like spicy foods, tomato sauces, fried foods, alcohol, sodas, black pepper.
your symptoms don't sound like gall bladder attacks.
prilosec would not help with gall bladder attacks, but would help with excessive stomach acid.
