First of all I hope you get to feeling better soon, asthma isn't fun.

Second - it is my experience that asthma comes and goes. My asthma has been very bad at certain times in my life, but as I focused on increasing my fitness and just being outdoors a lot more, my asthma has basically disappeared. I still have an inhaler with me, and really cold air is still a trigger, but most of my triggers have disappeared and I can't remember hte last time I had to use my inhaler.

Bottom line, for some people asthma does "go away", for others it doesn't. Congratulations on having a better ride with the inhaler
