I also am stage 4, bones and a couple lymph nodes, At the beginning I had 10 rounds of chemo. Was it rough,sure but I would do it again,(Dr. said I was finished for now) I finished that treatment last october, it's almost a distant memory. I get firmagon shot every month, take Abiraterone and presnidone daily. I forget about the chemo sides, now I get to deal with the sides from these meds. For sure I'm not telling you to go with the chemo, you asked how it is, You can get through it if that is the road you take. From reading what others say on here, I don't know if any the treatments are a walk in the park. Best to you on your journey.
