I've just taken advantage of the free Libre 2 scanner offer and, after 24 hours, I'm already impressed. I certainly wouldn't bother paying to have one full time but the free trial has already given me some insights as to what happens to my glucose levels around food and, most interestingly, at night. The pin pricks are useful but, for example, my blood sugar dropped to 3.5% mmol/l in the middle of the night. Something I would not have been aware of without the Libre 2. When I woke up it was 6.1 mmol/l but, after I'd dozed for another hour it dropped to 4.5% mmol/l. It then went up again to 6.3% mmol/l when I started moving. My usual fasting pin prick test could have been anything from 4.5% to 6.3% depending when I did it!!! I'm going to use it to really investigate what foods do what to my blood glucose over the next two week trial period. Like I say, I couldn't/wouldn't justify the cost for most T2s like me but it's definitely worth considering getting a free trial and learning from the insights it can give.
