But, it could also just be a combination of your cough hanging on and
quitting smoking has aggravated it. I waited to start
coughing up phlegm when I quit, but it never happened, even though I had a serious smokers cough.
It is common for an increase in appetite, however, I have been fortunate that this didn't happen to me. Just the fact you have lost your appetite tells me that MAYBE you still have some sort of lung infection. Please try to force yourself to eat a little more.
