We put down laminate flooring two months ago (Armstrong in the bedrooms and hallway; Mohawk in the kitchen).
Since the windows have been closed and the heat has been on, the last 3 weeks my eyes, nose, throat, lungs have been burning.
Could it be from the formaldehyde in the products? How do I get rid of it?

Yes, it could be but why not ask the tech line at the manufacturer? The only way to get it gone is to remove the flooring, IF Formaldehyde is present. It could also be an issue with your heater, have someone measure the CO levels.
