Hi, Jourdain2.
Answers to threads that are more than a month old don't show up in 'Latest Posts'. To help you out here, I'm providing a link to your 'update' post:
https://www.theanswerbank.co.uk/Body-and-Soul/Question1841973-2.html#answer-13636411
I suggest that anyone wishing to respond should do so on
this thread, rather than on the original one, so that their posts don't also get missed out from the 'Latest Posts' section.
I'm sorry to read of your brother-in-law's very rapid decline. Sadly, as the passing of some much-loved AB members (such as Mamyalynne and Woodelf) has shown, it can happen all too frequently in the latter stages of cancer.
