You can take antacid like Omeprazole 40 mg once a day before meals along with Domperidone 10 mg. Antibiotic like Ciprofloxacin
500 mg twice a day along with antiamoebic Metronidazole
400 mg thrice a day, will help in controlling the infection.Lactobacillus

If the problem persists, get yourself clinically examined and investigated.
