I have been on daily Azithro, Ethambutol, rifampin, for 2.5 years. Had my first neg in June but still on meds until next Feb. if all stays negative. I stopped nebs last November because of a cavity that developed in upper right lobe. I started using dry salt inhaler by Nevlers and areobika and the cavity collapsed and stayed away since I did that. I also raised the head of my bed 4" on my docs advice. My tinnitus is out of control so could be from the azithro. Waiting to talk to doc. This has been my second go around and it has been a big struggle not to lose hope.
