Ohhh!! Ae I always hear you cough.
I think you should see a doctor.
Before you see a doctor, you can take care of yourself by my suggestions below.
First, you should not go to bed late. You should wake up early and do exercise.
Next, drink a lot of warm water in the morning.
And you must avoid eating sweet snacks or foods.
Lastly, you should turn off air conditioner and turn on a fan instead.
^^ No need to take chemical drug in my opinion.
