Hot fluids (no caffeine) sleep and rest.
Nothing more to do. If you listen to your body and take 1-2 days of sleep and rest EARLY in the cold, you're set.
Case in point:
My girl and I both got the flu that's been going around town.
I took 1 (ONE!) day off work, not feeling too shitty, but still taking my time resting and drinking chamomile and peppermint tea until I was literally pissing it and even my shit smelled nice and fresh.
As a consultant, With my current rate, that meant some serious bucks gone.
She didn't take a break, but dragged her sorry ass to work every day, coughing and sneezing.
Of course she was taking over the counter cold remedies and vitamins (as I did).
After two weeks she's had to consult a doctor, take antibiotics for a week, take a few days off work and is still not completely over it.
At least she's employed, I don't even want to calculate what I'd have lost in pure $$$ that way.
Vitamins and cold remedies will support the healing, but nothing beats a day or two of rest EARLY in the process.
You'll be fine in no time.
