Hope, you give us HOPE! Merry Christmas and keep up the good work. Although the oral GSH doesn't seem to do much, we notice a big difference with inhaled...she clears and clears when we aren't doing it and stops when we start it back up. We do stop it when doing Tobi. I wish we would have known about GSH before the PA began to grow b/c my gut tells me it would have never appeared had we started it early.
