It is probably too late now but at the first sign of a cold try Emer- Gen- C. It is a powder high in vitamen C that you mix with water. An acquaintance who is a flight attendant told me that they all swear by the stuff to keep them healthy when being in the air all day in tight spaces with coughing and sneezing people. I have tried it a few times at the first sign of a cold and it seemed to work
However,I have been sick this week too. It came on really suddenly with no warning. I went to bed feeling great, woke up feeling like my head was in a vise. My husband has been downing the Emer-gen-C twice a day and so far so good.
