Answer 2

It's best to use them for 2 or 3 days and then stop. Cough suppressants and expectorants: If you're coughing so much that your chest hurts and you're getting a bad night's sleep, consider a cough suppressant such as dextromethorphan, Mosnaim says. Yoder recommends using cough suppressants only at night.
