[QUOTE="Scott-C, post: 1429740, member: 374531"] Sure, I found it worthwhile, subject to the caveat that I got it very shortly after getting the libre when I was mad keen on a new toy, so I might re-read it again having been using libre now for about 8 or 9 months and see how it stands up now I've got more experience with libre. One of the things I found interesting was his comment that because bg and ifg (interstitial fluid glucose, which is what all cgms measure, and then make an educated guess about what bg is) are different things (even though libre is meant to adjust for it), the chances of a meter and a cgm reading the same are nil; if you get the same reading, it's a fluke. It puts a lot of the whining I've seen on this site about, "oh, it's not the same as my meter" into context. Not going to beat about the bush on this point: cgm is incredibly useful, and if people can't recognise why they're different, they're weakening the gene pool. Reading the book, and using the libre over several months has got me to the stage where I've been able to understand the reasons for the differences, adjust for them in my head, and realise in some instances, differences are actually quite useful. For example, mine tend to run below my meter, so, if I'm out for a meal and a few beers at the weekend, when I might be tempted to insulin-stack, if the libre ends up higher than the meter, that's a strong clue that the IOB is doing it's job and no more bolus is needed. And if they're both fairly close, good indicator I'm generally stable because the bg/ifg gradient is close which tends to occur when stable. If they're far apart, good indicator I'm unstable, so will need to keep an eye on things. A lot of people expect absolute, definite answers from meters and cgm. They don't do that. They provide clues, circumstantial evidence. I can figure out the puzzle a lot more with cgm on top of meters compared to meters alone, so I'm not that fussed that they're different. [/QUOTE]
