Alright, so I woke up on my monday and my voice sounded a little nasal, but still, wasn't bad. and now today, my voice sounds like a dying cat when I sing! I have a singing performance solo I have to do this Thursday and my singing voice sounds terrible! The weird thing is, my throat doesn't feel scratchy or painful whenever I swallow something, it's just my voice that sounds scratchy. I also have been coughing A LOT and sometimes I won't stop after a minute or so. So far, I've been drinking lots of water, sucking on cough drops, and drinking hot tea, anything else I should do to have my voice good by thursday?

Thanks!
