How do you know when you have the flu?

Flu symptoms hit you suddenly and severely. They usually include:

1. Fever
2. Chills
3. Headaches
4. Aching muscles.

You can often get a cough and sore throat at the same time.

Tick all of the above!

Today seems to have gone on forever, have just wanted to sleep and it took all my energy just to have a bath this afternoon!

Away back to bed again!!!
