There was a woman up here near Sacramento about 5 or 6 years ago who was a contestant on a radio contest. Whomever could drink the most amount of water in a specific amount of time won some kind of prize. I forgot how much she drank, but it killed her, so my answer is yes.
Oops, I am sorry. I didn't even see your earlier post when I posted. I am not Louise Lasser (actress who portrayed Mary Hartman) haha, but I loved that show. I remember Grandpa - Mary's grandfather who was a flasher, and he got arrested. It was the most odd yet amazing show at the time.
