He passed out after throwing up alot and feeling very very weak. I've read the symptoms are very similar to heat exhaustion. He just depleted all of his sodium and they rushed him to the hospital and he was there for several days. It's was a few years ago but I remember he was down for a few weeks. He's a photographer & has to go out in the heat for shoots and after he was hospitalized, it was just too much. He was very weak for a while.I didn't know too much water could be that bad for your body!
What are the symptoms? How did they find out it was water intoxication?
Sounds like he should replace a few of those waters with Gatorade. I hope he is ok now.
