There's a bunch of things you can do, without even leaving your house. I got a cold the other day, and I wanted to get rid of it fast as well. Though, I still have the cold, I think I've found a couple things that do help! I researched it and put together a webpage about it- http://www.squidoo.com/getting-rid-of-a-cold . Go look there and get more info. Basically, eat right (don't eat dairy product or sugary stuff), drink alot, drink HOT stuff (this helps your throat so much), get some Vitamin C, get some fresh air, relax, de-stress, etc. Go look at my webpage - http://www.squidoo.com/getting-rid-of-a-cold for more information, and you can even buy cough drops or medicine or other stuff from right there! Don't even have to leave your house!
Hope you feel better!
