You mention that you feel like you are suffocating. Is that while you are inhaling or something that persists all day. With me, I would get a little tight while inhaling the nebs, but it would get worse throughout the rest of the day, to the point where it was hard to walk.
I have not tried tobi w/ the sidestream or the acorn. From what I understand you get less medecine in your lungs from the sidestream. That may be why you don't feel the same effect. It might be worth asking my RT about though.
I used the Acorn II in the hospital. What kind of compressor do you hook the acorn II nebulizer up to?
I have not tried inhaling fortaz.
Yes, I started exercising lightly on my rowing machine about a week ago.
