windwalker ---- thank you for your note. I saved it in my file. I had used Cipro as it was one recommended on the sputum analysis -- have used it two or three times. This time, I'm wondering if I might need a different one or if it means MAC is involved. I won't know that for two more weeks. I gathered from listening to Dr. Moua that he, too, doesn't always go for the big three treatment. He will try other things first. After 8 months of not coughing, I got very spoiled and just have felt depressed when it came back. I know it's not curable, but it was by far the longest remission I had enjoyed. Prior to that, only 3-4 weeks before I would be put back on an antibiotic so I think I was about to start dancing in the street -- thinking I was so much better. One other thing..... during the time I wasn't coughing, my nose was running and I could feel nasal draining so I started taking 4 Benadryl daily. I wondered if that added to the length of remission and had begun to think Benadryl itself was a miracle drug. (I had not used it in my lifetime previously). Guess not. Now, I wonder -- could the Benadryl have kept the cough at bay and let the infection build up in my lungs -- or did it play any part in the relapse. Just something I've considered. Wondering if you have any experience with it.
