With all the money and research that goes into medicine, it seems like they could come up with a really effective non-narcotic cough
I have a treatment for
sinus infections that helps, especially if they are really bad, but most people seem to think it's worse than the infection. Fill the bathroom sink with warm water, add a generous amount of salt, put your face in the water with your mouth closed, and suck it up your nose. Spit it out in the toilet, and repeat several times.
