Welcome to Mayo Connect but sorry to hear of the new diagnosis. One of the best defenses, I believe, is knowledge and education. Towards that end, I'm attaching a paper written by NTM guru Dr. Falkinham. Once you have a chance to read through it, post any specific questions you have about modifications you're thinking to make. Everyone here manages slightly differently, some being more risk adverse than others. What works for you might not work for someone else. Please be assured that the modifications are manageable. Take a deep breath, you've found a good place to ask questions and get support.
