Thanks for all the posts! Thats a good idea Grama-Herc, to remember to breath. I'll think of that next time, well hopefully there isnt a next time, but it'll be in my head. Yeah, they told me it was quite rare too, and found nothing wrong with me (took ekg, ct scan etc...) and said it was probally the stress of the triggers. hum?? I'll have to learn to deal with them better :o)
