Best ways to get over a common cold quick?

Also try two cap fulls of unfiltered vinegar in a glass of water. I do like the lemon idea, does the same thing. Will help your throat.
I hear pepper is really good for you. Try a small amount of that something sweet to drink after.

Eating oatmeal and mushrooms helps your immune system to build white blood cells...drink a lot of water, stay away from milk because it causes phlegm, and eat fresh citrus or strawberries for vitamin C. When I first get symptoms of a cold or even a stomach virus I will drink a glass of water with a lime squeezed into it, I do this about 4 times a day, and get extra rest...sometimes that's all it takes. Extra vitamin C and it helps to alkalize your body to make it hostile for germs to reproduce.

sauna... gets rid of runny nose, coughs, you are warm and can sleep deeply.. next day you are fine

Honey and cinnamon
