Wow, this was a most enlightening post. As background, my first panic attack coincided with me being dehydrated and needing emergency care. I was very dizzy and lost coordination which was pretty frightening. So now, when I experience dizziness (my doctor and therapist believe that my dizziness is caused by anxiety - but it could also be caused by my diet), I feel anxious. It seems to me that I should increase my calcium (and call the dietician!). Also, I had been experiencing panic attacks in the middle of my exercise and perhaps that is related to my 02 levels. Learning new things gives me so many tools to use - I love it!
