Beat It.

Because I live in a university town, I see the cold and the flu passed around quite often. I recently saw an instagram picture of a drawer filled with DayQuil, NyQuil, Aspirin etc. with the caption reading something along the lines of, "I've been sick for weeks and my drawer is piling up."
I am aware that I sound exactly like my mother when I say this, but usually when you get a cold, it is because you are sleep-deprived or over-worked. Taking DayQuil and powering through the day may seem productive, but long-term it is only a disservice to your body.

Here are some tips on how to get better:
Get miso soup take-out and eat it in bed:
Miso soup is essentially a light broth with seaweed and fermented tofu. It sounds iffy, but fermented food is great for you even when you're not sick and seaweed is a superfood that helps strengthen your immune system! Also, miso soup usually runs for under $4, so it's affordable and SO much better than a salty can of Campbell's Chicken Noodle. (If you're reading this in Burlington, Asiana Noodle Co. has great miso!)
Drink water and herbal tea:
You know this already.
Stay away from coffee and sugar until you feel better:
Coffee and sugar can make you feel temporarily energized and lull you out of rest mode. After their effects wear off, you are stuck somewhere suddenly feeling like you have been hit by a train. If you crave sweetness, eat raw honey (on whole wheat toast, in tea, in hot water). It's packed with minerals, antioxidants, and probiotics.
Stay Away from Dairy:
Whether or not you are lactose intolerant, dairy is not an easy food to digest. It also helps form mucus, which is the last thing you want when you are already sick. Give your digestive system a break while you are at your worst. Try almond milk instead!
Eat as may veggies as possible (cooked or raw):
This is just a good practice in general, but it's especially important when you are sick because your body can easily digest them, get the energy it needs, and focus on fighting off your cold.
Rest.
