Exercise-induced bronchoconstriction (EIB)

I’ve been running in the morning (about 1.5/2 miles) for the past couple of weeks, and after the first 5 mins I start to wheeze and my chest feels tight. After the run I cough a bit too.
However, I initially put this down to fitness levels being low for the last two years, and the fact that I smoke. Although I’ve cut down a lot with my smoking, and generally never really smoke mores than 4 a day.
I had a quick google and saw a condition called exercise-induced bronchoconstriction, and my symptoms seemed to match.
Also, I remember having to use an inhaler for a short period of time when I was about 10 years old, I can’t remember why, but it wasnt asthma.

Beside from grilling me about smoking (I am quitting, but very gradually at my own pace) are there any ways I can help prevent this?

I’m 22 shortly going on 23 if that’s any help, so age isn’t the problem.
