Wow to 1997. You did not mention Bronchiectasis but assume you have it! Wow to your age and weight and yet your exercise routine. I can only manage 20 minutes on a flat treadmill and I am 75 and weigh 99. Did you just do the IV Ceftazadine one time and have improvement that lasted? Often we hear that Pseudo only really improves after using inhaled Toby. But many people do not tolerate it so you are very fortunate indeed and your improvement is wonderful. I also have colonized Pseudomonas but mine is chronic infection. I also cough up what you describe at around 4 plus ounces a day. I tried the Toby inhaled but only managed to use 5 times (literally meaning 2.5 days). For me it decreased urine output so I stopped. It can in rare cases damage your kidneys. I also lost my voice totally but could have lived with that. If you keep using it eventually you could develop resistance. Some Drs. will rotate it with Cayston to prevent the resistance. But Cayston is usually approved only for CF patients. If your Dr goes to bat it might get approved. Otherwise it is prohibitively expensive. There is also Colistin inhalation as an alternative. But not sure what coverage that requires. The nice thing about Toby is that part B medicare covers it! Anyway I hear of some people using it for years and not developing resistance yet.
