Cough And Cough Non-Stop

I'm down with some kind of flu and viral infection. Sore throat pain reduced, but still with running nose and worse still, I cough non-stop. Those infectious phlegms are loaded in me and irritate my throat. It causes my throat to be itchy and I want to cough all the time. I just can't get a good night sleep.... :(

I didn't visit any doctor, as I am taking herbs. I don't want to take anymore antibiotics again. I am now trying to fight those virus with own immune system. Hope that I could be successful this time. It has been dragged for almost a week.
