My experience (and many other forum members) matches
@Energize comments: it depends on your CCG.
However, I want to add a note of caution - a Libre does NOT replace finger pricks.
It is great for tracking trends but it is not recommended for use with dosing and, if you are in the UK, it is not recognised by the DVLA for testing before (and during driving).
Some people find the Libre very accurate. Some people do not.
Some people find it pain free. Some people find they get nasty skin reactions. Some of these build up over time.
The Libre can be a great piece of kit and I would recommend asking your diabetes team whether you can have it on prescription. However, it does not automatically produce great BG and hB1AC numbers - if it works for you, you still need to put in work to get the most out of it.
If your CCG is like many and will not prescribe it for you but you decide you want to try it, forum members have found the cheapest ones are available from Asda and Superdrug pharmacies. And, having type 1 diabetes, you do not have to pay VAT.
