Thanks, KSH.. that sounds exactly the same as what happened to me. I'm glad she was ok, despite having to DNF... hard decision, but not when you cannot breathe.

I have an annual exam in 3 or 4 weeks and will discuss it then with the regular doc... (it will take me that long to get in anywhere else anyway unless I hit the er!)

I'm planning to hit the lake next Friday with my friend in her kayak -- I think I'll try no wetsuit first, then if going okay put the wetsuit on and see what happens. If I can't do it, I may scratch the tri until I get an exam and see what's going on. It is pretty scary to say the least. Will probably mess with my head a bit now!

Thanks for your support all.
I'll keep you informed.
