I had 25 sessions of EBRT radiation plus ADT. ADT wasn't horrible but I did ease up on physical activity intentionally lowering my heart rate during exercise and shortening my mountain bike trail riding milage. Emotionally flatter than normal. Everything seemed to require more mental effort to get going but was always rewarded by feeling better afterwards. I found that radiation side effects worsened over time and peaked for me around 12 months and sought additional medical assistance which has worked out well for me. It sounds like you are all in on this journey and couldn't be happier for the both of you.
