Having sang all of my life for fun I would have to say that much good advice has been past. A regular amount of sleep is the trick for my rest requirements between 6-7 hours a night. Less and I sing better low notes and more and I can't hit the really low notes even some that aren't so low.

The Main ingredients in Entertainer's Secret are Water, Glycerine, Sodium Carboxymethylcellulose(what ever that is), Aloe Vera Gel, and then Methylparaben, Propylparaben, and Potassium Chloride.

Does it work? I honestly can't tell if it is one bit better than a drink of water. I bought half a dozen bottles! They are designed real clever, you can not refill them with your own tonic or water.

I definitely do not believe it will help anyone recover from laryngitis irregardless how much you use. My voice teacher taught me no dairy, before you sing particularly milk, no chocolate, just stay hydrated with plenty of water.
