How do I fix my humidity problem in my home?
I'd start by adjusting the humidifier on the furnace. It sounds like you don't have to add any additional humidity to the air, so you could probably turn it down (or possibly off).  

If you have a gas fired furnace, turning the heat up a bit could help. If the furnace does not have an air intake connected to the outside, the air used for combustion will be drawn in from outside.  During the winter, the cold outdoor air has very little moisture. When the cold dry air is drawn into the house, it will lower the humidity levels in the home. This is why loads of people have dry skin in the winter, and the reason humidifiers are installed in the first place.

If none of that helps, you might have to consider installing a dehumidifier, or some other form of HVAC system to remove the excess moisture.
