I had a bit more time to read a bit of your bio this morning, its awful that they are not asking him how he feels as its the first thing my oncologist does.
As he has not started any ARB drug yet its worth asking why he can't have the Darolutamide. I think they all achieve similar results with similar side effects but you are right in that it may be a bit easier on him.I'm told my BP needs to stay under 140/90.
I'm sorry to hear about your son's problems but that dependence and helping your daughter out will give him a purpose, believe me the fatigue isn't nice but we learn to live with it and still get things done...just a tad slower. I still walk my dog for miles, look after my large rural property and cut wood for 2 stoves.
He will be worrying about his family more than himself,I know I was but it all gets a lot easier once settled into a stable treatment plan.
I'm following a very similar path as I'm currently waiting to see a consultant to talk about 6 sessions of radiotherapy to my prostate now that the HT has settled it down.
