if anyone has any tips on keeping them stuck on that would be great!
Every new libre user has lost one or two in the early days!
A few tips:
People often stick them on their arm without bothering to think about the state their arm is in. There's been people wondering why it falls off and it turns out they've applied it on top of moisturising cream - go figure why that won't work out.
To give the glue the best chance:
Shower/wash the arm to remove any grease and while doing that, also shave the application area with a razor - even if you've not got hairy arms, most people will still have a fine "peach fuzz" or random hairs, which are difficult to see unless you look up close, and that sort of stuff really doesn't help a sensor stick on, so shave it off.
Then dry, use the alcohol wipes, wait till totally dry, and apply.
Libre is not very high above the skin, but it can still be "caught" by a lot of unexpected things which can gradually loosen it and take it off: taking jackets/rucksacks/jumpers on and off.
Those often catch the edges. Many of us "librans" stick a 7 by 8 cm plaster on top to smooth out the edges a bit and pay attention to taking rucksacks off.
The other big thing is avoiding door jambs. I'm not kidding about that! I didn't realise how many times I bumped into door jambs when I was cutting a tight corner walking around the house or office or wherever, but I sure as heck realised it when I tore my 3rd sensor off doing exactly that!
Many new users apply it on the side of the arm. Try it further round at the back of the arm. It's less exposed there to random knocks which will build up over time to weaken the glue.
Have fun with it - it's a game changer if you don't bump into doors too much!
