@sounder27 I just thought I would chime in on the Arikayce. I have been on it since January 16. Interesting that your doc says one week on, one off. I am recommended daily, but when I lost my voice my doc cut it back to 3 times per week. That has really been my only side effect. I am back to taking it daily, as that is what is recommended by the drug company. It is very expensive, but they provided me a copay card. I pay nothing for it.
