Hi, earlier this year I switched from my old CFC (chloroflorocarbon) inhaler to the new HFA (hydrofluoroalkane) ones and now I can't condition at the same level physically because of my breathing. I've been diagnosed with moderate to severe exercise and allergy induce asthma, but with the CFC inhalers I always just took two puRAB before exercise and usually that was enough to get me through practice. But with this new inhaler, more often than not it barely opens my airways at all, just enough to keep me breathing. This has severely reduced the level of activity I can handle. I was wondering if anybod else has noticed a drastic change between the two.
Thanks.
