He changed me over to Xopenx - a different rescue inhaler. Like the Combivent, I am to use it when I need it and not more than once every 4 hours.
I think part of my problem is that I have a difficult time assessing 'when I need it'. And my expectations of what it feels like before and after are skewed/muddled/not clear.
BUT, I think maybe I'm making progress. Today I felt like my breathing was not as good as it usually is. So I took an inhaler 'hit' and, in a few minutes, it actually did feel a little better. In a few more minutes, I realized that it was actually considerably better.
Maybe I've got it noodled out... finally!
