Cough, Spit, Cough

I'm at the stage of my cold where I feel physically fine but all I seem to do is cough up a dark green pile of jelly every few minutes. It's always worse in the mornings for some reason, I guess that while I've been sleeping it's had time to settle. Luckily I have restrained myself from taking a picture of said jelly and posting it, there's still time though!
