Buffy,
Several people I know have had the flu. Emergen-C has been helpful for me, I buy it at Wal Mart and keep in on hand.

I have home grown and home made herbal remedies to use as needed too. Most grocery stores carry a line of herbal teas with some being recommended for relieving cold or flu symptoms.

A pot of homemade chicken soup is beginning to sound good so I may move in that direction....

Hope you are feeling better soon.
