This is kind of a new thing for me but I started having breathing issues last summer after catching a nasty flu

The cough never quite went away and it's been difficult to breath on and off ever since
So I finally asked my doctor about it and he gave me a sample of Symbicort and that seem to help the breathing but also gave me a headache and my ins. denied the prescription for it
So then the Dr. gave me a couple samples of Advair and that seemed to work better and without the headache but the ins. denied a prescription for that also
So now I am on my third type of inhaler called Flovent which has to be used with a second aerosol inhaler called ProAir which the ins. finally approved a prescription for
The thing that's bugging me is that the Flovent and ProAir are on two different schedules so I'm hoping I can coordinate the timing of each
Anyone else go through this kinda thing or have experience with this stuff?
