I was diagnosed with MAC and another bacteria over two years ago. Apparently, one is not good enough. Out of the ten antibiotics that were capable of working wonders on my bacteria, only 2 would be effective and only 50% of the time. Lucky me. Fortunately, my infectious disease (one retired and another took over) specialists, both discouraged me with starting the cocktail of drugs. They advised me to stay clear, because of obvious side effects, of the medicine as long as I was feeling o.k. Over the years the symptoms would come and go. For the last 6-7 months, I have (knock on wood or maybe gold) had minor flare-ups. For whatever it's worth (And I'm not claiming anything here), I'm a vegetarian and have been for 45years. (I'm 81)
MAC periodically reminds me that its still there, waiting to strike at any moment.
