I've been feeling a bit under the weather for about 3 weeks now. Started with a bit of random sudden onset dizziness, but has now settled into a bit of a cough, a little bit stuffed up, a little bit phlegmy, a little bit sneezy, a little tired.
I'm going away in a week and I don't want to still be sick like this, what are the best ways to get rid of a persistent cold? Vitamin C?
