A WOMAN drank herself to death with water after taking part in a radio contest to win a Nintendo Wii video game system.

Jennifer Strange, 28, from California was found dead by her mother after taking part in the "Hold Your Wee for a Wii" competition in which participants tried to see how much water they could drink without going to the bathroom.

Strange, who worked at Radiological Associates of Sacramento, said earlier she had a bad headache.

Radio station KDND 107.9 said her death was "tragic".
