Activate Libre whith stable bs?

[Antje77]

Hello, hope this is the right place to ask a question, first time posting on the forum.
I'm relatively new to having diabetes (type 2 or lada, on Lantus and NovoRapid) and I want to use my second expensive Libre sensor as I will have a weekend with long car drives and heavy partying
My bs seem a bit erratic at the moment (honeymoon?). I think I've read somewhere that the Libre works best when you activate it when bs is relatively stable for a few hours. Anyone know if that's right?
I really want to activate it now, but I don't want to make it work less accurate for the next two weeks.
(Don't worry, i'll still be testing before driving whith fingerprick test. And if my English is a bit funny it is because I'm from the Netherlands. And thank you all so much already for all I've learnt from reading hundreds of posts on this forum )

It is advised that you wear your sensor for 24 hours before activating it. Customer services won't talk about replacing a faulty one unless you have been wearing for that long since it is expected to be inaccurate during that time. There might be some truth in starting it during a stable period but I suspect that is simply because the Libre and the finger prick test do not give similar results especially when the blood sugar level is changing. There is at least a ten minute lag on the Libre. This makes them hard to compare.

Thank you. The first day it was a bit off, but wonderful to use while driving to see if I had to stop for a fingerprick test. I hope it was still a bit off during the first night, otherwise I have been hypo almost all night No more red wine for me.

I've found I need to wear my sensor for close to 48 hours before I can activate it and get sensible results from it. Otherwise I'll get a series of false hypo readings, especially if I lie on that arm a night. See below!
