I NEED TO GET RID OF THIS COLD?

I was sick starting Saturday night, when I was nauseous. Then Sunday I still felt the same, only milder. Monday I was congested and had a sore throat. Tuesday was the same as Monday, only milder sore throat and more congestion. Today is Wednesday and I am coughing a lot and only one side (I am assuming this means one gland) is sore, the other barely hurts. I am still congested. This is definitely a cold, I assume. The thing is, I am going on vacation with a friend tomorrow, and I do not want to spend my first days sick, or worse, I don't want to not go because I am sick. I have not been doing much to help this cold these past couple days, could you give me some tips on how to feel better tomorrow morning? Almost like a super cure! I know there are no cures to the common cold, but what about tips? THANKS.
