Hi
@Larryk 2 and welcome to the forum and this group of T1 ‘family’.
Yes, an Abbott Freestyle Libre is good for seeing what your interstitial glucose levels are doing. The readings are best double checked with a finger prick blood test twice a day as the sensors are calibrated at source and are sometimes set a bit above or below a blood test result, but as long as it’s consistent you can adjust in your head.
You need to scan the sensor with a reader - there’ll be people who can explain how to use an app on a phone instead of a reader - and it’ll give you graphs and bar charts that let you know what your levels are over 24 hours. As long as you scan every 8 hours it provides a good picture of how you’re doing and helps if you need to make any adjustments such as before using a bit more energy than usual or getting up in the morning and beating the Dawn Phenomenon which is when quite a few see a blood glucose rise.
For many of us it’s a game changer.
If you can’t get it prescribed on the NHS then you might be able to fund it yourself: the sensors can be ordered from Superdrug, currently for £35 VAT free (you qualify if you have T1), they last 14 days, but the scanner needs, I think, to be bought from Abbot, c£156.
Good luck and everything with the cancer, you’ve certainly had a lot to contend with and it’s great to hear you’ve had excellent treatment.
If you don’t want to use glucotabs to raise blood sugars then lots of us also do a bit of canabilism on a jelly baby or two - one jelly baby = 5g carbohydrate.
I see that you’ve already embraced low carb but if you want to widen your options you could also ask to be included on a Dafne course which takes you through ways to calculate insulin dose for carbohydrate eaten as well as a range of other useful stuff.
You’ll no doubt get lots of welcome and advice here so as has been said already, ask away if questions come to mind (or body).
