Wheezing in a smoker

While we await the next case, this was submitted by a patient:

I have been having respiratory problems for years. I am a smoker 2-3 packs daily. I have been taking prednisone and antibiotics for 6 months. My doctor had me do PFT's yesterday and the results were:

fev1/fvc% 80, tlc-59%, RV 3%.

I wheeze constantly, and wonder if anyone has any ideas before I see my doctor friday.
