@glynisd in answer to the question in your second post, I have a Libre, and swim a short distance five times a week - the sensor is fine in the water for up to 30 minutes, according to Abbott, and as I'm new to the Libre I haven't *quite* yet dared to exceed this - but so far, so good. Thinking about it, what with showering afterwards, it's probably wet for quite a bit more than 30 minutes, actually. I'm on my second sensor (it's very much a new toy for me) and it's all been fine.
I'm loving the Libre. I'm finding I'm much, much more relaxed about testing now - rather than testing 12 times a day I'm down to between 6 and 8 tests a day - the rest of the time I'm using the Libre (all the time!!!!) to get an idea of which direction I'm heading. I 'bip' to see if I need to test, sometimes - it saves a test strip. A lot of my blood testing has always been 'just to see', so this device is proving a Godsend. It's helped me to identify patterns, and make adjustments accordingly. It's reading around 20-25% higher than my blood tests, but as I'm aware of that, it's not a problem. I don't see it as an alternative to blood testing, but oh boy, it's a fabulous addition to the array of tools I'm already using to manage my diabetes.
I'm bordering on the obsessive where it comes to my 'numbers', and my control. Ironically the Libre has made me lighten up on myself a bit..... and that's FABULOUS.
Oh, and I did I mention that I like it?!
