I would say that I am an advocate for the FreeStyle Libre, but you should periodically check it against a finger prick, but they both have their inaccuracies. I am finding my use of the monitoring system very helpful, so looking at food intake, activity levels and so medication levels too. I had been cutting back on carbs for a month, but doing BSD for the last week, my 52 day average is 7.4mmol/l, but my 7 day is 6.3, so I am trying a day with no medication, been below 7.8 since midnight. The interesting thing will be what the reading is in comparison to a HbA1c test, but I do check odd results against the finger prick. I have sent information to my nurse and doctor, not heard anything back yet. I am talking to a medical service used by my client, they have a strict 7.8 or less requirement for travel to some of their Middle East sites. The monitoring system is expensive, but once you have reached and maintained your goal, well you can just periodically use it, so say two weeks every three months, maybe before a HbA1c. I should explain that I have come to this as my last HbA1c had come out at the equivalent 13.5, but what I was told was 10.1, just had not realised that it was the old % scale. Anyway, I have been fearful of lows with the Glimepiride, the increasing does and the advice to have carbs for my breakfast, I have seen levels around 3.8 on previous finger pricks, but it was pure guesswork, I was on a downward spiral. Monitoring system provides more detailed information, so I can do a cross reference finger prick and take appropriate measures, I keep dextrose tablets to hand, only used half of one as a precaution to get from 3.7 to 4.4, then the other half to get from 3.9 to 5.3. The culprit was excess activity on the day, so balancing things today. I took a month of observing and making small tweaks, before applying BSD, probably why I have seen a marked change in the last week!
