I have had the flu for a week now... help?

I have had the flu for a week and I still can't breathe right. I have my inhaler and I have taken a lot of cough medicines and mucinex and even prescribed pills to open my airways and I still have trouble breathing from time to time. Any homemade remedies anyone has to offer? I don't want to go to the er to get nebulized AGAIN this year.
