I can't believe that anyone falls for this "sheep in wolf's clothing" sharade...but i guess anything's possible when people are running out of methods and answers, and looking for a final solution. You may want to try and brush the white coating with a tooth brush; or there are products that you can buy to remove that white residue off your tongue. Don't look to a desperate salesman, who uses other people's misery for profit, for answers. Also...try listerine after you brush your tongue.
