Sleep is good
Also, I dont know whether its been proven to help, but Ive been drinking green tea for years (I have IBS and sometimes my stomach is funny with milk), and I hardly ever get ill. I had a cold about 3 weeks ago that my family had, everyone's lasted about a week, my cold lasted two days Twinings green tea with mango, and twinings with orange and lotus flower is delish
I'm feeling better today, seem to be getting rid a lot quicker then everyone else I know.
Eating lots of soup, drinking lots of water and orange, sleeping LOTS and just generally trying to avoid mopeing around and feeling sorry for myself
