Hi all. I'm back from trip. Thanks to all of your help, I had the tools and systems in place so that everything went okay, and I now know that I can successfully travel internationally! I bought the Pari Trek S which worked beautifully (at home I use the Ombra; with the Pari I was also able to connect my Aerobika). I also bought the Drizzle Pot -- the first night in Europe, I had forgotten to twist the disc on the bottom from 120 to 220 volts, so the water boiled over, and we also blew a fuse in the hotel room. However, once I realized that I needed to manually move it to 220 volts, everything worked fine after that. I bought dish soap in both Denmark and then again in Italy. I couldn't find distilled water anywhere, but in Copenhagen, I used demineralized water, and in Italy, I used purified water (bought at a pharmacy). The one minor issue that I had was that the nebulizer cup for the Pari Trek had a sort of chalky residue on it, even after boiling it for 10 minutes in the drizzle pot. Not sure why that happened. Next time I travel abroad, I will bring tongs with me to use for dealing with the equipment in the boiling water of the Drizzle Pot. I will also bring a collapsible bowl.
I was traveling with my 20 year-old daughter, and I was worried that I wouldn't be able to keep up with her, but I did! I made sure to do airway clearance every morning before starting our day. We then came back to the hotel and rested for 1-2 hours each afternoon before dinner; during that time is when I would soak and sterilize my equipment.
My pulmonologist had prescribed antibiotics for me to take with me just in case I got sick there. I felt good knowing I had them and felt even better that I didn't need them. Overall, the trip was a success. Thank you for all of your helpful suggestions!
