Congrats, DS. I truly hope that your SRT is successful. I've been watching for your postings regularly and am very glad to hear you had minimal side effects.
My PSA actually dropped last month (to .06 from .07) so I'm holding off on SRT for a couple more months to see what my PSA does. But like you, I've come to terms with my own situation and accept that I will need SRT at some point.
I hope you can make the Dec cruise. It will be great to shake the hands of a fellow warrior.
