I had asthma (cold and exercise induced) really bad when I lived in MO, but since I moved to CA (15 years ago) it hasn't been much of a problem.
Now, one hit of albuterol before the start of a cold double century (usually start before sunrise) is all I've needed . . . until yesterday when I had an attack on a really easy ride with my wife. Hit me hard but I breathed my way through it since I didn't have my inhaler along.
Agreed, you never get as many dose out of an inhaler as they say you should! Anyway, all I've needed for the last several years is Albuterol and even that not very often, so I'm not complaining!
