Thanks for your comments.. Tena, I first took Brewers Yeast about 25 years ago and though I would gag to death. I had this recipe for "Tigers Milk". I began to get used to it, then I started to love it. I have more energy when I take it, and it seems to diminush the side effects of my sinemet. More evidence that we are all different. I don't get fleas and my hair is shiny....now I know why
