Hello I share your concern. Looking at your description, your symptoms are suggestive of gastroenteritis or indigestion with acid reflux due to stomach hyperacidity. I would advise you to take antiacidity medicines like pantoprazole or ranitidine group of drugs with antacids and antiemetic drug like domperidone. If you continue to have diarrhea than you may require a course of antibiotics preferably ofloxacin or ornidazole group of drugs. Meanwhile maintain good hydration by taking lots of fluids including ORS and fruit juices to counter dehydration and electrolyte imbalances. you should take soft diet and fresh fruits and chicken and junk food like noodles. Hope this helps you Best wishes
