I have stocked up on essentials that mean I will be able to eat if I'm ill (and up to eating).
I have stocked up on paracetamol and other medications.
I have talked to friends about being flu-buddies, and make sure that someone knows I'm ill and okay.
Right now I am going about my buisness as normal and paying attendtion to handwashing, if I get it, I get it. I would rather get it out of the way sooner rather than later.
As for the anti-viral... most of the nurses I know are saying they probaly won't take it. I have not made up my mind, what would affect my decision is, on the day, how bad do I feel and will the tablets get to me in time to make a difference.
I'd be keener to take the antibiotics if I got a secondary infection.
