I think Cindy brings up a really good point about docs reliance on FEV1 as an indicator of IV time. I have a doctor who listens to me and will start me even if my FEV1 does not indicate it at that visit and sure enough my FEV1 catches up with my symptoms; but, in the mean time we have gotten the ball rolling. I think it is important for us to communicate well to our doctors and know when things are not right regardless of FEV1. Thanks for pointing that out Cindy.
