Great topic!
I have asthma and am having huge issues right now. 2nd time this year I have had bronchitis, as a result of a sinus infection. This is week 2 of the horrific never ending cough and lunge tightness and it has taken me pretty much off the bike and put a huge dent in my race season. I am on Advair and my regular inhaler, but don't feel a difference. I took last week fully off the bike b/c with the sinus infection I also had a fever and was trying not to have it drop into my chest, but that didn't help. I have ridden easy this week and just want to be able to breathe again!

I can ride easy or just below tempo and be ok, but anything with speed and accelerations(so group rides and races) my lunges pretty much shut down and i fall right off the field.

Good timing with this, definitely going to try to get some of my medications changed.
