@cowgirlmt , Being in a medical field, I am sure you know to learn all that you can about your disease and treatment. Ask your doctors lots of questions. Please take the time to read past posts to learn more about other's experiences with this disease. A good person to read behind is @katemn. She has left us a treasure trove of good info. Please be aware that doctors are divided on how to treat this disease. For example: my doctor at the Mayo clinic does not want me to ever take azithromycin because it is one of the more powerful drugs. He does not want my MAC to build up a resistance to it over time, because MAC usually comes back later in your life and you don't want to run out of options for treatment. Mind you, that is MY doctor's opinion, and there are members that went on the same treatment you are on and seem to be free of the MAC for years. Have you reported back to your doctor that you are still feeling so rotten?
