At the height of training I’ll drink 3 gallons per day, and haven’t yet suffered any ill-effects, despite some people’s predictions to the contrary. Is it really bad for you? I eat a lot of salt, so I figure I’m just flushing it out. [/quote]
Wow man. Three gallons sounds a bit excessive (even if you are on gear). There was a lady who just died of water poisoning several months back. She drank an entire gallon of water in 1 hour
It’s not uncommon to hear about people having heart attacks related to magnesium deficiency, and there is some speculation drinking large amounts water void of this mineral is contributing to it (the purified bottled water craze).
Now I am not saying you are going to drop dead, it hasn’t happen yet, but besides any UN-likely health problems you will have, there is no need to drink that much. Half your bodyweight in ounces and that you get from foods, should be adequate. If you feel you need more start from there and increase it.
