<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had a chronic cough with phlegm for over a year now. I barely get any sleep, and I sometimes cough so hard I throw up. I have been on nasonex now for 6 weeks and my cough has actually gotten worse. I have been tested for allergies and have none. My doctor says its post nasal drip. How else can it be treated?  <response>: Hello rearward welcome to Chat Doctor.come have evaluated your query thoroughly.
