Colds

It's Cold season here. The weather keeps getting warm then cold, then warm then cold again. We have been passing colds around since November 10th. Lexi got sick, then I got sick, Eugene got a little sick, (I was still sick) then Lexi got sick again, now I'm coughing, sneezing and have a stuffed head. And of course, Eugene is coughing, and Lexi is coughing still.
We haven't been taking too much medication, every once and awhile we'll take something, but if this continues we might all have to check ourselves into a drug rehab program by the time we're all healthy again!
Anyone else struggling with colds?
