My wife has asthma. I'm posting this on her behalf. She has an inhaler that was prescribed by her doctor, but she has trouble, especially when climbing. She wants to know how others deal with this. She says she reaches a point in a long climb where she has major difficulty breathing. I know the obvious answer is for her to creep up the hill at a snail's pace. Just wondering if anyone else has similar issues and what they do to deal with it.
