Hi Sue - I just wanted to send you a quick reply that may help ypu. I saw that you also are from the NJ area like I am. I suffered for over a year from 1/2001-5/2002 until I was diagnosed. An elctrophysiologist/cardiologist at Monmouth Cardiology Group of East Brunswick NJ did the tilt table test and together with an endocrinologist, they diagnosed me finally at Rob Wood Johnson Med Center. I'll spare you all the long details of my story, feeding tubes, gi problems,etc,etc,etc, but if you need more info from me let me know. I hope you get help soon so your symtoms can atleast get to a controllable state so you can function a little better. Also, breathing is a problem for me, but I use a ventolin inhaler, only as needed when my breathing gets very bad and that helps me with it. Also, if you do not over exceed your limits, breathing is better. As soon as I feel my breathing getting labored and I start getting even just a little dizzy or tingly or ears ringing or any symptom happens, I sit down wherever I am for a little while until the feeling passes and that seems to work for me. Have a good night funnyfrog in NJ
