As I started this thread and Rog suggested it was more suited to the Health forum then I will leave it in the capable hands of the moderators: Jessicas dad, Mr’s mix, Lucy as they have had experience first hand iirc.
All I know is my best mate had a good job, a mortgage and decent holidays abroad until diagnosed, then he was out of work almost overnight. Meanwhile on the other side of the pond in Europe another driver / workmate with exactly the same diabetes was sunning himself regularly in Barbados while sticking needles into his more than ample folds 
A common sense approach at last for many who have never had a hypo or suffer with it.
