Hi,
I also have the cold at the mo and I'm totally shattered!!! I never get the cold. Haven't had the flu, think I'd be out of commission for at least a few weeks though. Are you working as well or did you take sick? Don't over do it, take it easy and sleep when you need to, I also strongly agree with upping your fluid intake. Take care, rest on the sofa with pint of water in one hand and remote control in the other, surrounded in tissues, brilliant!!
