I have been cleaning with 409 every day for the last week, and am losing my voice. I also have asthma and have had several attacks, since the trees and grass are now growing in our area. The last time I had this much trouble with my voice, it was discovered that I have acid reflux. I have been taking Omeprazole for the last 3 days,using an albuterol inhaler, taking certraline (generic zyrtec) and using Flonase. Is there anything else I can do? How long will it take for my voice to get better?
