[edit] Steps

If your fever is 100 or under don't take fever reducer (like Tylenol or ibuprofen) unless you have problems with seizures. The fever kills the virus and is actually beneficial.
Mix 2 teaspoons of apple cider vinegar, 2 teaspoons of honey (or more if you wish) and fresh squeezed juice from 1/2 lemon (this is helpful but not completely necessary) to a mug of water that has been boiled. Stir. Drink this three times per day.
If hungry, eat homemade chicken noodle soup with lots of fresh ground pepper. Also, eat spicy and garlic foods like hot wings.
Keep your resting area clean and sanitary.
Suck on zinc lozenges, do not chew them. Take according to package instructions.
Take regular baths and wash your hands after any exposure to your cold. Also clean clothing, change bed sheets (priority), and surfaces that you may have exposed to avoid re-infection.
Use a vaporizer or humidifier.
Use a microwaved rice sock on your head, ears, neck, or wherever you have muscle aches and discomforts.
Be sure to get lots of rest and drink a lot of fluids.
If symptoms persist for more than a week, see your doctor.
Remember to use everyday manners, such as covering your mouth when you cough and sneeze.
Eat an orange, gets lots of vitamin c!
Drink hot soup!

[edit] Warnings

Always ask your doctor if there for any medical reasons, you should not try these methods.
Use caution when using vaporizers and boiling water around children since steam from vaporizers can get very hot, while a child can pull a pan down from the stove.
