I know a really good way of removing a Libre 'cannula' - you walk it onto the edge of your open motorhome bathroom door and it rips them smartly out before you can say a word. Not even painful! Very efficient indeed ...... didn't even fall out of the short sleeve of the T-shirt I was wearing.
NB - I hadn't realised before seeing it out - that it has a vicious spike on it - so has to go in the sharps bin, not the rubbish bin, when you've finished with it. I expected it to be like a pump cannula and assumed the introducer needle must be in the inserter. Nope, that just goes in the ordinary bin.
Libre rep inserted my first (on a small hospital trial at my clinic) and insisted that one didn't have to wait 24 hours and that lying on them made absolutely no difference. So she deemed the arm I usually lie on to be the absolutely best site, to prove what she was telling us. In which case - it's totally useless on me. Over the 10 days it lasted, ONE reading matched my Insight meter value - and the difference twixt meter and Libre was as little as 1.5 and as high as 6+ with no pattern like a certain %age difference, or closer on lower ones, the differences were as random as the actual readings. For two or 3 whole days according to it, I was hypo most of the day, going down to 1.9 at times. Admittedly a couple of times when it said I was high 1s to low 2s, I was in the high 3s to low 4s - but other times it would say I was 2.5 and I was really 8 or 9 ....... always a reason like I'd not ever so long had a sandwich so I'd expect it to be what my meter said.
I have got another couple of sensors - but can't say I have much enthusiasm, still - I'll stick another in the other arm tomorrow and activate it Tuesday and see what occurs. Perhaps since I now have the firm expectation I'm wasting my time - instead of thinking 'what a brilliant way it is of doing a basal test' - I won't be? LOL
