It is so important that you rest your voice. Otherwise, you could be causing more damage and the laryngitis could last even longer. Just curious, do you have a cold virus or do you think it is from overusing your voice (talking too much)? Especially if it is from overuse, try your hardest to not keep overusing it. Also, check with your doctor if it persists for more than 2 weeks because that is the average length of time for laryngitis. Any longer could be a sign of a more serious problem. So rest, rest, rest your voice, drink a lot of water, stay away from too much caffeine and alcohol (they dehydrate you), and if you smoke, try to cut back as much as you can.
No I'm not a Dr. I'm a speech pathologist in training and just took a very intense course on voice disorders (laryngitis is one of them).
