Hi What Can Treat Laryngitis (acute Starting From A Flu,

Hi what can treat laryngitis (acute starting from a flu, no bacterial infection) if resting the voice is not possible? I lost my voice for 2 weeks and have it mostly back now but as soon as I start talking during my day the coughing starts and gets worse to the point where I am coughing violently and it brings me to tears. I just started a new job so am talking all day and I can't take time off after a month on the job...
