After coming off Sprivia last week coz of urine retention and feeling fine, I fancied going without fostair as well (I switched last week from seretide) and have been breathing better today than I have since my flare in January. Did a 50minute 25k cycle without any problems. Honestly breathing feels great and have found it much easier to clear phlegm today as well.
The other strange thing I've noticed today was during exercise whenever I consciously do diaphragm breaching my oxygen sats dropped slightly from 97 to 96/95 but as soon as I startts breathing normally through my mouth again they went back up.
All a bit strange
