I have lost my voice, what can i do to get it back? And will it return by Tomorrow?

First you gargle with 4 ounces of warm water and put 2 teaspoons of salt in it. The longer the salt is in the back of your throat, the better the results will be. Yes its better if you dont talk. Theres no way to tell when it will come back. Just gargle like 4 or 5 times a day.
