IS MY NEW HOME MAKING ME SICK?

O.K., so I just bought a new home. We took out the drywall, painted, there's no carpet. But, me and my kids are experiencing really dry throats in the morning. Everyone also seems to have a bit of runny or stuffy nose syndrome as well. I am trying to chalk it up to just the cool winter (we are down south) but, this has never happened before and I don't want to go on ignoring it. I have not tried a humidifier yet...that is my next option. We had a home inspection done prior to moving and that panned out just fine. Does anyone have any ideas? Have we overlooked something??
