How can I get my voice back quickly?

I have had this happen many times. I suck on cough drops. I also drink hot tea with honey and lemon. As you drink it swallow slowly so it can coat the back of your throat. It is also good to drink allot of water. Humidifiers are also good. If you dont have one take a hot bath with lavender or some other relaxing scent. Breathe deep. These should help! Good Luck at your performance!
