Query: It didn't work for me

I bought this and the vocal eze product. I sing a wide variety of songs, from raspy rock to clean smooth styles. I suffer from spring alergies and was hoping this could get me through the rough spots. I actually lost vocal range with this stuff and couldn't get the normal growl in my voice for the rock tunes. It was awful. It could be that the throat issues were alergy driven, but this stuff was supposed to help. I will not buy it again. One good thing is that it tasted pretty good so if you are more interested in nice flavour rather than results, its not bad.
