Like many above, my problems usually start with the onset of colder weather. During the warm weathrer I'm pretty much asthma free. When it's cold I use the steroid inhaler on a daily basis, then keep an albuterol inhaler in my seat pack . . . just in case.
It has bailed me out in a couple of bad situations but overall the steroid inhaler keeps me (pretty much) asthma free. I just have to remember to use it!
