I have been up and down all night trying to cough up all this phlegm in my chest and I am so sick of it. I'm basically over the cold but because of all the phlegm, I can hear wheezing when I lay down and it bugs the hell out of me so I try to cough it up and nothing is working!!!! I wanna sleep and I can't because I feel vibrating mucus in my chest and it's starting to piss me off.
