@georgemc For my biochemical recurrence, I received a six-month Eligard injection 3+ years ago. It was very effective at lowering my testosterone level, which rebounded to almost normal in less than a year. Side effects lasted more than six months, however. I did have hot flashes but they were more annoying than severe. I was tired and took naps but this may have had more to do with the radiation than the injection. After about 7-9 months I lost some but not all body hair, which did grow back. The most bothersome effect was frequent urination. I was peeing 20 times a day and 3-4 times per night. Even if I did not drink anything after 8pm, I was still waking up multiple times a night to visit the bathroom. I do not miss that at all. My PSA is still undetectable so fingers-crossed that I will never need ADT again.
