Had it in mid-November, and was sick for about 2 weeks (including the entire 10 days of the first vacation I've had in 2 years)
I got some prescription-strength cough medicine from the doctor, and my husband did all of the driving. We also delayed the trip for a few days to wait until I was no longer contagious. I don't think I would have made it without the cough medicine.
Just a side note, but the flu is a virus...antibiotics will not help with the flu at all. They will only kill a bacterial infection, such as a sinus infection or bronchitis or pneumonia resulting from the flu.
A good cough medicine (rx if necessary, so you can sleep & your immune system can regroup), decongestants, expectorants, and lots of fluids - especially chicken soup - are the best thing. If you get really uncomfortable, you might find it helpful to put your head over a pot of hot steaming water with a towel to keep the steam in, or to sit in a steaming shower for a while. A few drops of eucalyptus oil or Vick's rub in the water is nice, too.
