Reflux uncontrolled: many times reflux and heartburn cannot be controlled w Omeprazole alone. lifestyle changes can help, avoiding alcohol, spicy foods, fatty foods, tobacco, nsaids and tomatoe products can help as well. increased saliva is also seen with reflux. your doctor would likely double your Omeprazole dose or change medications. black stools and vomitting blood would definately be red flags to be seen for.

Stomach pain: Sounds like a peptic ulcer. You probably should have an EGD (scope exam). Cease all alcohol consumption. Avoid all NSAIDS. H. pylori infection is relatively common. Consider taking 14 days of Clarithromycin and Amoxicillin and add Pepto-Bismol. (Obviously under care of a physician.)
