Hello aerogirl, I take omeprazole and famotidine to help with acid reflux symptoms and when combined, I have few to no problems with reflux. I don't eat at least three hours before I go to sleep and I monitor things like chocolate and tomatoes . . . foods that have caused trouble for me in the past. I eat them but not at night. It's pretty much under control though I do have concerns about using both of these drugs together over time.

I, too, was a cyclist. I was never competitive and never did long trips but generally cycled 13-16 miles five or so days per week. I can't do it now; I don't have the lung capacity. I had my upper left lung lobe removed last June and am on the three antibiotics currently. Really no ability to breathe that deeply without needing to stop and recover. It has never occurred to me that cycling habit/activity contributed to MAC lung disease but I suppose that's possible. As far as quitting, boy, if I had the capacity I'd be on that bike. I hope the cycling didn't contribute and you can continue because it sure is fun. My best to you.
