It feels like a Chronic Cold. When will the madness stop!?

As long as you have a runny nose, you will continue to have coughing. Mucus from your nose also runs down the back of the throat and irritates the sensitive tissue. If you're coughing up some sputum, that's great, that is your lungs working to clear themselves. It sounds like you are on your way to getting better already. I recommend Robitussin DM for your cough, it has dextromethorphan in it to ease the cough, but also has guaifenesin (sp?) to loosen up the musus in your chest, making each time you cough more effective at bringing the crud up. Make sure you spit it out and not swallow it. You might also consider using a cool mist humidifier in you room at night to help ease any dryness in the throat.
