Sore throat and cough?

Hi a couple of weeks ago, I had a very bad cold. It took a long time for me to recover, then i felt fine during my april vacation week. Now the vacation is over, and I think I've caught another cold. I've been gargling salt water for the past few days, and recently started to drink alot of oragne juice. I need to feel better in a week, can you suggest anything to get me to recover? My throat doesn't irritate me that much, but I've had some coughing that gets annoying.
