Hi Howard,
Sorry it looks like it is back. Is the plan ADT for life or are they thinking of zapping pelvis with RT? I have to say with 6 nodes involved it seems this is in your lymph system and could have spread further.
I think the ADT and the beer will have no interaction. Side effects of ADT are not dreadful. I was on it for two years. You will probably lose all interest in women from a sexual point of view, but they are still delightful.
I was just about to mention Chris J's inspiring story, and see he has posted. The best thing about Chris' story is that he put off ADT for about five years. So you don't just have to do what the doctors say when they say it, but if you do go down that route you have to accept responsibility for your actions.
If you ignore all treatment you probably will die in about five to ten years and it will not be a pleasant life, if you make decisions about your treatment you might not live much beyond ten years but it will be reasonably pleasant, for most of the time.
