@alleycatkate I looked up NAC on NIH and Mayo sites. Certainly worth trying. Both sites say that it is effective as an antioxident, it breaks down mucus, is an anti-inflammatory, and is also used in psychiatry to calm OCD, bi-polar, and schizophrenia. It helps restore the liver also. It contains sulphur, which is an antifungal and has amino acids which is protein to build muscle and tissue. It comes in pill form as well as an inhaleable. Can buy ovet the counter, but suggested that you get prescription strength. I will ask my doctor about it. Thank you for the post.
