I'm so sorry that you're dealing with such a frightening and disruptive condition! I've not had the situation you describe occur, but my reflux can make me short of breath sometimes, and it LOVES to make my throat tense and tighten. Now that I'm on two Nexium a day, most of that has stopped. The fact that you're on three a day would please my allergist/ENT, who strongly believes in aggressive treatment for reflux into the throat. I get the mucus thing too - and surprisingly, allergy meds have also helped me recently.
I have no answers or advice for you - just wanted to let you know someone's listening. I hope others will post soon with their experiences.
