Hi,
@dougscrewe , now that libre is slowly starting to be prescribed more, some official training videos for both patients and doctors have been produced by ABCD, in the link below, which explain how it works and how to interpret it, so maybe have a sketch at those, you don't need to register ir anything, just click the linked videos on this page:

I started using it about 3 yrs ago, was a bit meh about when I first heard about it but though will give it a shot. The first day I was wearing it, I scanned it, saw that my bg was getting low and dropping hard, checked my bg on meter to confirm, then had some sweets to raise. That would probably have been a messy hypo without the libre. Avoiding that hypo sold me on the idea, and I've been using it ever since.
As time went by and I got more used to it, I realised there was a lot of other things it could be used for to just gently steer bg levels, just by being able to see bg levels moving around.
If you're being offered it on script, I'd definitely say go for it.
Good luck!
