@swl1956 Unless you have heart issues or some other justification, I doubt any insurance company is going to pay 20x+ for Nubeqa as generic Zitiga. Probably why your doctor does not even want to try. You did not say how many months in you are except that it is 12+. If you want it to be ,24 months that is your choice. No doctor can force you to continue. All studies show decreasing benefit as months are added. A few recent ones show zero or even negative benefit when non-PCa factors are included. As long as the NCCN has 24 months as a standard of treatment most doctors will not tell you to stop. No risk to them if it leaves your bones hollow but they could have a malpractice suit if you have a recurrence shortly after stopping. Therefore, you will need to take charge of your own treatment with respect to months of ADT.
As mentioned, you should be doing weight exercises to keep muscle, high impact to maintain bone, and take low dose Tadalafil 5mg (no Viagra at that dose),
Wish your treatment is a success.
