If you don't have one, ask your doc for a cough assist device. I ended up in the ER from the one cold I've had In 8 years as C7. I had almost blacked out twice from an inability to clear the phlegm from my throat. When I went home, the doc prescribed me a cough assist. It works for clearing my throat. Sorry for continuing the hijack, but this thing may save my life someday. Of course, that would depend on me clearing my throat preemptively (which I started doing for as long as the cold lasted) or being within quick rolling distance when I have the complete blockage.
