Lingering laryngitis - What to do?

"I was diagnoised with bronchitis four or five weeks ago. I am finishing up the second round of antibiotics. I still have laryngitis. What can I do to get rid of it. I have tried just about everything. I still have mucus in my airways. I can't talk very well. I need some suggestions as I have exhauted all I can think of. I have lost weight and missed time at work.
