DEFINITELY!!! Google "water intoxication"
Can you die from drinking too much water?
Yes you can. Drinking too much water can lead to body tissues swelling up from trying to absorb the water. The brain takes allot of it and leads to menengitis or brain swelling. This can cause seizures and the amount of water you would need to consume would make you throw up and exscesive vomiting can lead to vasoconstriction and cause a heart attack. This happened in a college hazing ritual in a fraternity. The one of the two kids died.
Drowning ?
Don't think so :L
Yes, if you drink way too much water at one time you could definitely kill yourself.
Oh yeah, a lot like drowning yourself, like Arthur says, in your lungs. There have been ases reported and one on the radio, a girl died did it from doing a game with it.
