I'm in a similar situation with metastatic cancer in lymph nodes and 10 years since prostatectomy. I've been on eligard/orgovyx and zytiga(with prednisone) since October 2022. --- My suggestion is to stay active, i also work at a computer and take 3 small walks during the workday and have 2lb weights to do light lifting during conference calls and webinars. I need 9 hours of sleep to be well rested, otherwise i get tired and/or have to rest after work. -- stay positive and active, that's my advice
