i use to have asthma really bad as a kid then it got better. only needed meds every once in a while. a few years ago i had an asthma attack for 2 weeks straight. couldn't sleep or lay down or anything. had to do with nail products that leaked in my bathroom. i finially broke down and went to the dr and got in big trouble (good thing my dr was use to me showing up a few weeks later when things were pretty bad, did it once with a malconcussion.) so she gave me an strict regimine of drugs. felt much better.

since moving to cleaner air i have no problmes at all, except once when i first started cycling, but that had to do with a number of things.

moral of my story: don't do what i do and get it checked out if your worried about it. better safe than sorry.
