Sore throat, painfull cough?

I recovered from a fever a good 2 weeks ago, however my throat seems to still be fairly sore, my cough wasnt that bad yesterday, but this morning i've woke up and it worse then ever, i am also coughing up phlem. My nose also seems to be fairly runny as well. Any ideas what to do to get better fast? As im driving for 5 hours to stoke next monday!
