Hello Bernard,
Welcome on your first post after a year of following comments. I read your profile, it's nicely written describing a difficult path. I can't comment on your treatment except that Christie's is one of the top cancer hospitals so you must be in good hands. Also different people react differently to different drugs and there are a number of combinations.
I joined the Macmillan forum but found joining more than one to be more reading than I wanted and if you want to join in even a short reply can take more time than you think. Macmillan tend to send a lot of emails, very few of them about Prostate Cancer and they often reminded me when I didn't want reminding. So I decided to focus on this one who very rarely send emails and specialise in Prostate Cancer. Although I have had a couple of Macmillan nurses who do a great job, so support the charity.
I store interesting points in Microsoft Notes although I find if I want something it's better to search again in case there is new information.
I also watch a YouTube channel called Prostate Cancer Research Institute with a Dr Mark Sholz. Although YouTube can also nag you with suggested videos so you need to give topics a rest every now and then.
I hope to read more about your progress and wish you all the best.
Peter
