A bit technical, but very good guide to CGM and things like TIR, TBR and TAR etc and reading and making sense of data.

I agree with your assessment of that, as a techno dinosaur who OK was allowed a one month trial of Libre yonks ago (version 1 of the programing and not allowed access to download the App) so all there was to go on was which way the arrow showed on the screen of the reader until after 28 days it was downloaded at the clinic and there wasn't a pattern to be seen anywhere so I shrugged my shoulders and forgot about it, though recently I have thought more than once that I might try another go, because everyone I know with them seems to have so much more info on things which have never even occurred to me, but make sense to take an interest in, except of course without a Libre I've no way of reasonably accessing the info.

Very nearly threw this laptop on the floor and stamped on it last week when one of the Links posted to something happened to contain a Link to NICE Guidelines for D so I clicked on that and scrolling through the 2nd doc, happened to notice that in T1 they should be advised to test BG after meals and their BG level should be between X & Y at 90mins after the food.

It has NEVER EVER been suggested to me, to test after a meal by any HCP. Only necessary for BG to have descended back to '5-ish' immediately before my next meal. And that's what made me fume! I know damn well, it's been engraved on my brain with a chisel that T2s ought to do exactly that when 'testing what they can eat'. So not having T2 I should ignore that.

Just flippin aaarrgghh. I've stopped mixing in academic diabetes circles for far too long.

My Libre reader shows me "daily patterns" which I find helpful and it is clear from it that my BG has two noticeable dips, both slow and steady descents, one during the night, regardless of my overnight Levemir and the other a similar slow decline between 6pm and 9pm. Other small peaks and troughs through the day are due to food and Novorapid but those 2 are clearly due to the Levemir. I am now starting to get a handle on getting the right dose of Levemir and BG level that I need to go to bed on to keep that waking reading in range and to have a small snack like a couple of prunes in the early evening (if I am not having dinner or eating late) to keep me from dropping too low.
Jenny,I would really encourage you to give it another go as I think there is now a huge amount of knowledge to be gained from the info it provides.... even just the stuff available on the reader, as I haven't got any means of down loading it to Libre View yet.

I had a telephone consultation with the doctor at the hopsital recently, not having had any bloods done since last November, and not having been asked to provide any Libre data to them, and the first thing she wanted to know, was my Time in Range figures. I think that’s becoming the most useful benchmark that the HCPs can go on.

@Bruce Stephens - it may well be, but our CCG use their own course, based on BERTIE. I absolutely don't remember being asked to do it, but it was over 10 years ago and I was having a mental breakdown at the time too. I'd been asked before that if I'd like to put my name forward for a pump but said because of the mental probs I was having, I didn't think that would be such a brilliant idea. Once I solved the mental conundrum some time later, and corrected what was causing it, I decided I ought to give a pump a go.

Anyway FWIW it's that TIR scenario I really would like to 'have a go at' without having to be accompanied 24/7 with a ruddy alarm clock! :) (or making dozens more holes in my fingers - they are starting to object a bit sometimes by now)

I am sure I have seen on Twitter DAFNE saying they are starting online.

My comment was ambiguous. I meant to say that I was sure I'd heard someone saying that it was DAFNE advice not to test after meals, but rather just to focus on the readings before meals. I presume it's usual advice now to care about readings between meals (though not necessarily to always test then).

And obviously as continuous monitoring expands, I imagine we'll all be advised to look at Time in Range and in general reducing variation. (At least, until closed loop pump and CGM systems become commonplace.)
