Hello. I just wanted to share that for two of my relatives, taking N-acetyl-cysteine (NAC) has been extremely helpful. For the youngest relative with recent onset, the supplement seems to have stopped the symptoms altogether.
For the older relative, he reports that it is the first thing he has tried in a long time that has helped (but not cured). Both experienced results within a week. May be worth a try if ok’d by doctor as NAC has great safety profile. A couple articles with more info:
