How can I get rid of most of a cold in 2 days?

Yesturday I woke up fine... then in the afternoon I started feeling tired with a scratchy throat! then I thought to myself "sh*t! im going to wonderland in 3 days!" I got really upset, I started getting ALOT worse. I burned up, I actually had a pretty high fever which isnt that normal for colds, and I had diarrhea, but I drank 3 gles of oj and took 500mg of vitamin C My fever went down within a few hours and by bed it was gone and my throat was feeling better. But I just woke up because Its almost impossible for me to sleep good when im sick... and now my head hurts, throats scratchy and my nose is pretty runny and stuffed up. my whole face hurts right now. Any natural ways so I can feel alot better for wonderland on sunday? I have 50 or so hours to get better. or, well on my way to better... anyone wanna help me out? please xx., 10 pts to the person who helps :D
