I cough up a lot of phlegm in the morning mostly, when I brush my teeth I usually gurgle to get it away and then it sort of comes out instantly like vomit.. 

even after doing that more is to come that day! it always screws up the way i talk and makes my voice 'break'(?)i have to cough to get it out of the way for a few minutes so i can speak

the colour kind of varies, from creme to yellow

lately i haven't been eating too much and there isn't as much as there was before but it's still there

how would I get rid of it?
