How to get my voice back?

I've got a cold and I lost my voice. I need to go in to work tomorrow and I need to be able to speak, I have a meeting with my supervisor to discuss implementing a project...
How do I get it back! I cant eat or drink anything, it comes right back up...

You sound too ill to go to work - whatever the circumstances. Just a lost voice is fine - I could give you advice, but if you can't eat or drink anything, you're way too ill to go in! Your supervisor won't want your germs, think of it like that...

I already missed the meeting last week because I had to take my friend in to the hospital (which is how I got sick!) I have to go in!

if you tell your boss he will understand... most likely if you go in, they will just tell you to go home.
