I think it's working, but I don't have conclusive evidence at this point. I will have pulmonary function tests in two weeks again and I am also getting a home FEV1 meter so we'll see what they have to say.
In general, I am feeling well (despite the horrible humidity) and I am getting alot of stuff out because it is nice and thin. Sorry to be disgusting, but I describe it as my phelgm is now like watery gravy instead of thick pudding.
