That annoying tickle

When you feel like you're getting sick, you know that tickle. The thing is, it seems to be all I end up getting. Third time this winter I have this "tickle" while friends & family come down with a full blown cold or flu. I guess it's good that I don't get completely sick, but it's still annoying to have this tickle, fearing that the next day i'll wake up in misery. But they linger for about a week and then fade away.
