Sorry,
@Ruthlavelle , we've kinda derailed your thread a bit by going into the details of "torture by armpit hair and sticking plasters" (something the FBI have obviously missed in their attempts to interrogate ISIS suspects - waterboarding is weak compared to armpit hair stuff...), so, to get it back on track:
If (a) you're able to afford cgm, either dexcom or libre/blucon/xdrip+, or (b) your ccg will fund libre (and then you pay a 100 quid to put a blucon on top), definitely go for it.
Cgm is almost like cheating. It makes T1 so much easier. You can see your bg moving in more or less real time, so instead of making massive corrections to sort a hypo or hyper after they've happened, you can see it starting to trend out of range, and then just nudge it back with 5g or 1 or 2u, no drama, no crisis.
If any half-wit asks you why you're wearing a small bit of plastic on the back of your arm, tell them that it makes your life a lot easier.
I was dx'd about 30 years ago and have always paid attention to levels for the simple reason that I'm not at all interested in going blind or losing limbs.
That's been a hard ride with strips alone, but is so much easier with cgm. If you're able to get it, get it.
