The common cold is so "common" that we tend to take it for granted, that if we dont take the necessary actions, it may just drag on and on... becoming infected, and dubbed a "stubborn flu" that refuses to go away.
I had just went through such an episode, which I hope will make me wiser in the future. Started with a dry itchy cough, innocent enough. But as I continued to eat whatever I desire to eat, and not sleeping early enough, soon it festers and developed into an infection.
To cut the long story short, I went through 2 rounds of antibiotics, and went into a cycle of "almost recovered", and back to square 1, at least 3 times. I was getting tired and frustrated with this "stubborn flu".
A friend in church was surprised to find out that I'm still "suffering". She mentioned that I should "fortify" my immune system with Vitamin C. A simple advice, but like a lightbulb that suddenly light up in my mind, I realized why didn't I think of that??? (Or perhaps, I knew what all the right thing to do was, without really following it)
I went home, down a cup of Vitamin C effervescent (1000mg), and did the same the next morning, cooked porridge for breakfast, lunch and dinner. Another dose of Vitamin C, and multivitamin at night. 2nd day, same routine, porridge for all my meals again.
Now that I'm into the 3rd day, I can confidently say, yes... that worked! I have long ran out of my medicine, and only took cough syrup (DuroTuss Forte) these 2 days. I made sure I slept more than usual, take my Vitamins, eat my porridge obediently, and stayed away from "sinful" food religiously.
If you are suffering from a "stubborn flu" as well, perhaps its time you take charge and be a responsible steward of your own body/health. Drink lots of water, take plenty of Vitamin C (it cant be stored, and will be flushed out of your system anyways), eat porridge *smile*, and SLEEP!
Hope this simple advice will speak to you, just like how it spoke to me through my friend in church. :)
