Wow, that's a totally new one to me. At frst I thought it might be something in your tap water, but you say it's bottled water too...
Have you been able to figure out any thing else? Does it happen with ice cold water? Room temp water? Fizzy (carbonated) water? Does it happen if you drink a full bottle at a time? Does it happen if you sip slowly over time? When you have bottled water is it spring water? Flavored water? Distilled water? Enhanced water?
Just some questions that could help pinpoint what the issue might be. Wish I had an answer.
