Jayne, this has been around for a while. Search for it on the Internet and you will be able to pull up the clinical trial documents. As you can see from the responses to my original question, it does work. One SNAFU after another has postponed the beginning of my treatments, but I am definitely going to have it. Spitting is high on my list of necessary skills (grin). It is also known as Ethyol, so you can search for that too. Good luck!
