Martine, one more Stage 4, 5 years ago, here. Two things will work in your favor: 1, you are in great physical shape; and 2, you have a positive, can-do attitude. Both make a whale of difference when things start to get ugly about week 5. I had both and it was much easier for me than many of the patients I saw every day. Just remember this is a small part of your life and it WILL be over. And while you are going through it, there will always be someone here who can answer any question you may have. The OCF provides one heck of a cyber support group!
