I would like to introduce you to David Emerson ~ FLHW (David E). He has been specifically down this road. Here is his blog site:prostatecancerat42.blogspot.com
He also started a foundation at www.flhw.org
and has an email address there as well.
You and I are close but I have not progressed to a rising PSA and I believe that your were further along when the disease was discovered. Still I stay hopeful and positive, and send the same well wishes to you. You can find more guys like yourself at the Infolink social network, as well as the the Prostate Problems Mailing List found at www.ustoo.org
Second line drugs like Keto or Nilandron will work for a limited period. Moving to chemo sooner may have it's advantages in that many clinical trials require failed chemo to enter the trial. Abiraterone is one such trial. Also note that Provenge may be an option for you as early as summer next year. So maybe looking into how that will be available might be a good move for you now.
May peace be with you and your family. Never lose hope!
