Help how can I stop and cure coughing from the flu?

I went to the doctor had the flu got medicine but have new symptom today. Coughing. I feel better even began cleaning & have nonstop coughing. I’m drinking hot tea now and have cough drops but what can cure coughing? I was inside all day but went out to buy soup and it’s cold so now coughing got worse. And it’ll be raining next few days. 🙁
