Steve, your feelings remind me of John's when he 1st entered treatment. For him, I think the fear stemmed mostly from feeling a loss of control of his life. If that "fits" for you, here is something you can do to get back in control- PROMISE yourself that you will stay as well nourished and hydrated as possible during treatment, discipline yourself to a schedule of food, liquids and rest over the next few months.You and only you can really controll that. Anyone who can jump out of an airplane or ride hell for leather on a mountain bike can handle the treatment. Best luck. Amy
