Thanks to everyone who posted a reply, they were very helpful. I have decided to have the 6weeks of rad. I will start about Feb.5th. Now I am asking that anyone with suggestions as how to prepare and endure please post any help you can offer me. I am going to gain all the weight I can before starting and the Dentist which I saw today said all my teeth were OK and would give me a priscription for toothpast with high floride content. He didn't know anything about a Tray which I have herd mentioned here. So please, ir you have any advice please let me know. Thanks Again
