Sorry to hear about your progression. I think the main reason they don't give out timeframes is becasue they don't know. We have seen guys go for years, and some go for months. It is so dependent on where the PC goes. If it goes to the bones, it may be a long time. If it goes to a vital organ, it could be a short time.
I assume you saw the thread about Jevtana. Chemo is not considered curative. It may be that your best hope still is in the HT. Can't really worry about the potential side effects in this game in my opinion.
I am not in your situation yet, but with a Gleason 9, I really expect to be at some point. I have just tried to live each day as the best day I have left, telling those i love that I love them, doing some things I've always wanted to do, and enjoying every sunset I see. I could be hit by a bus tomorrow, while I am waiting for the PC to rear it's ugly head again.
Good luck to you. Have you considered seeing another doctor ? It could be that a different approach may add some time, rather than just stopping the HT and doing nothing.
