Twiglett, poor you, much sympathy. I've had it too - spent all Monday night puking in a bowl while sitting on the loo (more info. than you wanted maybe?) and have felt like death warmed up ever since. Dh has been off work for two days and I could not have coped without him.
Ds1 was sent home from school this afternoon, after being sick, and has thrown up ever since (has been asleep a couple of hours now so I hope the worst is over).
Just waiting for ds2 to succumb now....
On silver lining side, have lost 6lbs in two days.
