How can i catch rid of this cold?

I have a sore throat, horse cough, frenzy and runny nose. How can this go-away? Is it only a cold or is it the flu? Rest. Hot lemonade. Sleep. Stay well-insulated (tons of blankets). Warm baths. Vitamin C and Zinc. Eat fresh citrus and feed your body. Feed a cold, starve a frenzy (isn't that how it goes?)
I have a cold recently but it go away. I always enjoy some nice hot lemon water to stop it and it works.
