Well, I love to hear about folks who are improving! Yay! Keep it up, Barb! “Whatever works”, right? BTW, the Driscoll Theory protocol is changing soon! We absolutely still need Diamox, but after a few months of Zyrtec/Zantac, my kids and I were able to go down on the antihistamines! I no longer believe that mast cell activation syndrome is a huge part of our problem — more of a red herring, but it needs to be treated. So you’re not on Chromolyn or Ketotifen? Those can help, and I wonder how much of our decreased need for antihistamines is due to those medications… Hmmm… I hope to be able to bring answers for our continued symptoms, even after antihistamines . Big hug…
