@tinaesims Absolutely "Why not?" I just finished a year and a half or the Big 3, 6 months of it daily! We traveled and traveled, as well as wintering in our Texas home. I had to make some adjustments due to fatigue and some gastric issues, but otherwise we really enjoyed ourselves. I come from a long line of people on-the-go - my grandparents continued to travel in the '70s with serious heart disease and Parkinson disease, my parents with multiple health issues, my uncle with emphysema... We now live winters in a senior-ish community where nearly everyone has serious health challenges, but keeps on going anyway. Far better than sitting on the sidelines and feeling sorry for oneself! And portable nebs are definitely the way to go - my InnoSpire Mini was under $100 with battery (you have to search for a good price) and lasted about 3 years. If nobody comes up with an affordable alternative, I may just order another.
I forgot to say, when we travel, we carry a "cleaning kit" - a small storage container with dish soap, clean paper towels, and a bottle of peroxide for cleaning and sanitizing the neb parts, Aerobika, and husband's Acapela. The cleaning routine is part of our evening in the hotel.
