Hi Chiarimom, I’m so sorry to hear of your son’s struggles! This is complicated and because I hear of so many struggling with these sorts of questions, I will be releasing some videos soon about this. It takes picking apart the pieces very carefully. At the webinar-type videos I will also discuss how maintaining a certain pH level may help keep Diamox working (there is information in The Driscoll Theory for you). You may want to look into Thera pH (at http://www.VagusNerveSupport.com) that can help, too. Gentle hugs to you both, Dr. D
