I suggest adding mullein and lobelia to the nebulizer (one part each to five parts colloidal silver) and also the Clear Lungs Extra Strenght orally.
You know, I always advise alternating with probiotics when taking lots of silver over a prolonged period - but to be honest, I know lots of people who have taken lots of very good silver over a prolonged period, including in my own household and family and friends, and I have never yet heard of a one of them having a problem with intestinal flora being out of balance.
That includes myself, btw. I don't take CS every day by any means, but when I do take it I take a lot and I have taken it for several days in a row many times.
