Thank God others can relate to me and thanks for the replies.

Rubylizard, I think I neglected to mention that for me it works both ways. If I feel nauseaus, 90% of the time it turns into a panic attack and then vomiting. But it also works the other way, too. I could also be legitimately sick and vomiting will turn into a panic attack.

It's been about 4 months since my last attack, but I make sure I'm never far from a bathroom because I couldn't stand the embarrassment of having a full-fledged attack in front of strangers.
