EIA or VCD? Can't breathe!!

OK, I have had exercise induced asthma (EIA) aka exercise induced brochospasm (EIB) for years.  I had it fairly well under control until the last few years.  After several pulmonary function tests it was discovered that I also have vocal cord dysfunction (VCD) caused by reflux.  Surprising since I never even felt heart burn, but I guess with the larygeo-pharyngeal type that is not uncommon.

So here's the deal - I am now on medication (Aciphex) to heal the damage and have been feeling better.  I have been slowly improving my run speed (my most challenging event) and my breathing has felt better in training.  I was excited to see how I'd do in a race.  Then I have my first tri (sprint) of the season this weekend and towards the end of the bike I feel things getting tight.  By the time I am to the 1 mile marker I am hardly moving any air!  I had to stop and walk three times!  Totally sucks.  Also sucked that apparently my inhaler fell out of my jersey when I put it on in T1 and I didn't notice.

Has anyone else had to deal with this type of situation? Is the VCD rearing its ugly head towards the end of race - or am I just having an asthma attack?  I am so frustrated!  I was having a good race until I couldn't breathe.  I don't want my whole season to go like this... your advice and suggestions are appreciated.

Thanks everyone!
