Yes, in fact when my lungs started detoxing, for about 2-3 months, I woke up several times a night gasping for breath, and had to go into the bathroom so as not to disturb by husband because I would just cough and cough and try to catch my breath, all the while this white foamy metallic tasting stuff was spewing from my lungs. I would have to sit on the edge of the toilet, taking puff after puff of my rescue inhaler, just to get to the point where I could breathe well enough to get back to bed. Only to get up a couple hours later to do the same thing all over again. It was hell. But, I lived through it. These days, I may get a slight, but only slight return of symptoms when I have a candida flare.
