@kimmiek I think you will find the support you are looking for in this group. I have found everyone to be helpful and caring and it is so great to be able to share things with others who understand because they have the same disease. You will find lots of info and suggestions to help along the journey. I am 65 and also have COPD and MAC. Are you taking your probiotic at least 4 hours outside of any of the antibiotics? That is important, otherwise the antibiotic will destroy the good bacteria in the probiotic. Azithromycin & Ethambutol can be taken with food, which can helps to alleviate nausea. Rifampin should be taken on an empty stomach (1 hr before or 2hrs after a meal) so I found evenings good for that one, to sleep through any nausea. I am glad you have your son and his family for help and support. Wishing you the best, I will include you in my prayers.
