And now ... my bro is testing assiduously. The first thing to go was conventional bread and I've alerted him to Lidl HP rolls and Livlife. And then he gave up beer. When I see him at Christmas I'll ask him about his BS levels.
Meantime he and his wife are quizzing me in detail about what I would like to eat when we go there on Boxing Day. I think the right information a little at a time enables them to digest it.
I haven't got him a book yet
but he seems to be more interested in what happens to me.
Btw his glaucoma op went well and his sight in that eye is improving. The other eye will be done in due course.
I'm very pleased, so thanks again.
