Years of breathing fumes in a race car has given NASCAR driver Rick Mast carbon monoxide poisoning that will end his career.

Mast, who has not raced since May, said yesterday that he is suffering from acute and chronic carbon monoxide poisoning that carries symptoms similar to "the worst hangover in your life."

"You wake up feeling nauseated and you want to throw up and you can't," Mast said. "Your head is pounding all the time and you just feel awful."

Mast, 45, who made 364 starts over a 15-year Winston Cup career, said he began feeling ill in March but didn't get out of the car until May. It took dozens of visits to various doctors before he was finally diagnosed in November -- he said he lost 43 pounds in that time -- and there is no timetable for when the poisoning will be out of his system.

The only thing he knows for certain is that he can no longer be around chemicals that are spinoffs of carbon monoxide, an odorless, colorless, tasteless gas that is in everything from a car's exhaust to poorly ventilated heating systems.

That means everything from racing cars to using a lawnmower and riding a tractor on his Rockbridge Baths, Va., farm are off limits to Mast.
