For what it's worth, I have had a completely different experience with oxygen than what was described to you. I have used oxygen on and off for about 9 years now. I have used it for a few months at a time and been able to get off of it for long periods. This latest episode has been tougher. I've been on for about a year straight now. I work a high level, full-time, very visible job and just cart it with me. Would I prefer not to have it - sure! But it's not going to limit where I go and what I do if I can help it. I take it up to visit my daughter at college in Flagstaff (8,500 feet at the ski resort), and I make arrangements to have plenty at the beach in San Diego for vacations. I have never had nose or ear problems with it. It is possible that with more exercise I could get myself off ot it, but that's not for certain. Still, I'm going to work toward that goal. I have never had to increase the amount up - it's not something that your body gets used to one amount that then requires you to up the next higher dose. The only reason to up the dose would be if your lungs got progressively worse.
I think each person needs to consider what he or she wants out of life. If you'd rather live somewhere else, but deal with O2, go ahead and do it. The other option is live an unsatisfactory life where you can say "well, at least I'm not wearing ozygen." And what kind of quaility life will that be for you? I am into quality, not quantity of life. Lucky for me, I've had both, having reached nearly 55 years later this month. Before making any final decisions, get some more information from those who are experts in oxgen, not just those of us think we know about it. And good luck, whatever decision you make. Remember, there is no right or wrong decision - just the one that works for you personally.
