Hi David, They have checked my thyroid 2 times, at my request, and and was told that my test results were normal, whatever that really means. Last time I asked about a specific test one of my Doctors said "how about leaving the Doctoring to me?". I said I was going to do the Ironman again after I completed treatment but not sure thats in the cards at this point in time. I'm thinking about taking up cage fighting instead;-))). I figure I could take out some of my aggression and anger with regard to all these wonderful side effects I've encountered. I read the side effects of Cisplatin and see that I was blessed with each and every one of them))). So right now I'm lifting weights and riding a stationary bike 1-2 hours a day. I'm actually still not ready to get my Bike out of mothballs and hit the streets again;-(((. Maybe next year? Thanks for the kind words. Steven
