HI I am a 35 year old female. My height is 1.69, weight is 107kg. I have been suffering from a post nasal drip for more than a week. This lead to a cough which is quite persistant, hence it sounds dry but there s little bits of phlegm sitting on my chest making me to cough to bring it out. I have taken Borstel, Phensydal, Prednisone, and also honey with lemon and cinnamon. I am miserable of coughing continuously, please help. TIA
