Emily:

I still struggle up hills but not because I'm not moving oxygen to my muscle, simply because my muscles are tired from all the riding I've been doing during my summer break. I can tell you that my BF has noticed a big difference in my breathing when we ride together (he unfortunately has seen me during one of my nasty asthma attacks while attempting to get up a hill or two). I can tell you that I'm amazed at what a difference the new inhaler has made in my lung function. My asthma doctor has me using QVar and Albuterol together and it does seem to be the magic combination for me and my lungs. Good luck in pursuit of better breathing.
