Hi,
@ChrissiStar , welcome to the libre club!
Sugar Surfing by Stephen Ponder and Beyond Fingersticks by William Lee Dubois, both on kindle, have a lot of good tips on how to use cgm well, they helped me a lot when I first got libre.
I recall from an earlier post you're in Scotland?
The rules on libre prescription are a lot looser than those in England, so there's a fair chance you might be able to get it free on script.
Each area here does have slightly different policies, unlike England where there is a national policy, but, for example, where I am in NHS Lothian, they'll pretty much give it to any T1 who wants it, so it would be worthwhile asking your DSN.
There's also a small transmitter you can buy for £139, MiaoMiao 2, which reads the sensor every 5 mins and sends the results to your phone and watch. This version has only come out in the last days so I don't think anyone here has experience of it, but plenty of folks have used the first version and found it to be reliable.
