You might try talking to your doctor (oops! you said not to say that!) about switching drugs and trying different things. you might also find a doctor that is used to working with athletes - most doctors think you're fine if you can climb a flight of stairs but we know there are more important (and intense) measures.
My doctor put me on Singulair to help my asthma but its delivered a dragon punch to my allergies. we're still going through a process of guessing to figure out whats best for my asthma.
