It is a very simple cure - not for the weak-minded! If you're afraid to do this - I don't blame you - but it's all in your mind. If I can do this, without vomiting - you will be able to also (I hope).
All you need is Cayenne Pepper.
Take a small glass and pour in about 1/4 teaspoon of Cayenne Pepper. Add a few tablespoons of warm-to-hot water to the cup and mix it around the best you can.
Then Gargle with it - and spit it out. You may need to do it a couple of times for it to work - and may be fine after the first try. All I know is that my voice came back right away. It wasn't 100% back but it was at least 70% better than before that. And if hours later my voice started to go away again - I would do this again and it would be back. This really worked for me. I can't vouch for everyone on here - but it honestly worked for me. And I didn't get sick from doing this either - but don't swallow the stuff and be careful to try not to get it on your lips. It will tingle or burn!
Feel better soon! Also, the other thing which soothed my sore throat and overall ill feeling was taking some theraflu tea. Hope this helps and take care!
