Thank you both, @Caz1 and @iserbrown for you advice and information.
@Caz1 thank you for sharing your story and I wish you all the best for next week. It is so hard isn’t. I feel divided and have not slept that well in past few days. I have tried to research and speak to a range of people which has equipped me with some questions I really want to discuss with the surgeon. Like you, just want to read a good book and switch off.
Thanks also to i@iserbrown as I will look at those articles tonight.
Cheers
