Dear Jon, I am most sorry to hear that you have all had the dreaded flu! That is not nice at all. My grandma used to make us have a big bowl of oxtail soup when we got the flu, and a pint of Theakstons 'Old Peculiar', that worked! Then when we were getting a bit better loads of steak and kidney pies! Always worked for us!
You get well my friend.
Regards.
Neil.
