Hello doctor. My girlfriend is sick from last 3-4 days. It all started with her feeling nauseous and then she started vomiting and having loose motions with fever and chills. She was vomiting everything that she ate. Her doctor has put her on antibiotics and now the loose motions have stopped and vomiting has reduced. But everytime she drinks water or some liquid, she vomits. If she drinks water, she vomits soon afterwards. She is feeling weak and her stomach is paining. Her antibiotics dose is still to be completed. What should she do?
