How do I get this goddamn phlegm out of my throat?

I’ve gotten some kind of a throat cold and consequently there is such a large buildup of phlegm in my throat, i’m having a bit of trouble breathing.
Right now i can’t breathe without making this wheezing noise. It’s really beginning to bother me because it’s at the point where i can’t get sleep.
Any advice is appreciated.

Well I always found that by tapping-banging the back of your neck with the edge of your hand (or, better, someone else’s) would break up the phlegm and subsequently making it easier to hoik.

Go to the doctor if you feel it’s necessary, otherwise just buy an expectorant at your local pharmacy. This way, you’ll have a more productive cough and can spit it out the window of your car.
