Losing my voice

I don't know how many of you have had this cold that just won't go away, but it is truly horrible. I woke up this morning with almost no voice. I'm able to talk, but it doesn't sound good. All the coughing is just making it worse. One of my co-workers lost her voice completely, so I'm a little nervous. She sounded like me in the beginning. Fingers crossed tomorrow I still have a voice.
