How can I get my voice back?

I lost my voice and I'm a music major at my college... How can I get my voice back ASAP!

Have a hot cup of tazo chai or green tea with honey. Take some ibuprofen or advil. Rest. Relax. There's actually a lot you can improve with your singing, if that's what kind of music you're majoring in, without your voice. Play whatever you're singing on the piano, work on form and presentation, lip sing.

You could gargle salt water.
I'm a singer, and that has helped me trememdously in the past.
Good luck!
