I drank the water|
If water causes you pain, it's either too hot, too cold, or not actually water. Are you sure it's water? It could be acid of some kind. Is it acid? If so, don't drink any more than the recommended dose. I did that once, and ever since then I couldn't sing soprano.
Nope, it's definitely the water.
It was a great temperature, too - very refreshing.
:( i'd give you a hug, but that might make things worse...
