Hoping so very hard for him that it can get sorted out very soon.
It's a nightmare with Abs, it can take a while to find the one that works - all the more important for us all to understand why we need to avoid them except when absolutely necessary.
It's not 'us' as individuals, it's 'us' all together, the infections and viruses somehow develop resistance to each ab for all of us, not each separately
Of course there are times we really need them, and can't recover without - tricky,isn't it.
Vibes by the bucketload for Wm (((xx)))
