Us too!!!
DD got a virus/cold early last week, DS started with it last Friday, DH called from work last night complaining of a sore throat.
I'm taking DS to the doctor today - he's better and definitely on the mend, but I want to get his ears checked, just in case. Don't need ear problems at 30,000 ft.
I started pumping DH with OJ, Zicam, and lots of fluids. You've got time to get over this! Push fluids, get lots of rest (I didn't read all of the other posts, but I'm sure they said the same), and definitely get to the doctor if you think it may be a sinus infection. 3 days on an antibiotic will work WONDERS!!!
Oh, and don't forget the power of positive thinking!!!!

That's what I'm counting on to get us well in time for our departure! (and Zicam, Vit. C and fluids of course)
Hope you feel better and have a great trip.
