This is all dependent on your level of exercise and rate of perspiration. A 72kg person would have to drink around 6.5L of water for it to become dangerous[1]. [1] http://www.sciencelab.com/msds.php?msdsId=9927321 http://www.sciencelab.com/msds.php?msdsId=9927321

Sure. My case is a bit unusual as I'm far above average in height and weight. On average, the recommendation for my size is around 5.0L/day. In relation to that, the top of my head figure of 3.8L seems like a good lower bound. It's always interesting trying to do conversions in a world made for folks are 5'8" and <200lbs. I'd be shredded to the bone if had a 'healthy' BMI and I'd be dropping pounds a week on a 2000 calorie diet.

Interesting fact - a healthy person's kidneys can excrete 25 litres of water a day. Drink more than this, and you expand your total body water volume to dangerous levels, which can lead to swelling in soft tissues and lungs (which can be life threatening). This happens in patients with psychogenic polydipsia. Of course, drinking anywhere near 25L is not 'safe' either, and can still cause electrolyte abnormalities, neurocognitive dysfunction, seizures... Stick to the recommended intake, adjusted for water losses during significant exertion or high temperatures.

Unless I'm mistaken, water poisoning is only a credible threat when you consume exclusively those high volumes of water and nothing else to raise the salinity of the water in and around your cells. Over the course of a day, most of us get (much) more than enough sodium from other sources to eliminate any risk of water poisoning from 3.8L of water per day.

  Yeah -- similarly to you, I'm pretty convinced that water poisoning is only a worry if you're unwell (mentally and/or otherwise) or do unusual things like water-drinking competitions.

Ecstasy and water poisoning are related. Ecstasy makes users extremely thirsty. Water poisoning related deaths at raves have been reported. About 6 L is enough to put a lot of people in a very dangerous place.
