I've had asthma since the age of 5 (I'm 42 now), and it's always been mainly triggered by exercise. I've noticed over the years that all of the literature about EIA (or EIB as it's now apparently called) says that you should just take your reliever 15 minutes before exercise to prevent wheezing during exercise. I don't know about anyone else, but that's never worked for me! No matter how much I prepare, I will always need to use my reliever several times within the first 10-15 minutes of exercise (particularly hard exercise like running), and then my lungs settle down and I don't tend to need it for the rest of the session.
So my question is to anyone with similar asthma to me - have you ever been able to prevent wheezing during exercise? I'm sure I can't be alone in this, and my asthma nurse hasn't really been able to give any useful advice. I love my running, but I'm not happy that I still have to take quite high doses of my inhaler in order to enjoy it!
