Little late for this house. Wife and I have just got over it (flu) and its a 12 on the one to ten scale.
Not only does it give you the runs and pukes, but it comes with the massive headache and every friggan joint in the body hurts. I advice is when you all get it to have a bucket handy as you'll be a'sittin and chuckin at the same time. And we both puked till we started chucking up that yellow bile or whatever it is. Dry heaves are a bugger.
I never remember being this sick before
Glad you're on the upside of the upchuck.
