I got my 1st FreeStyle Libra and I am in love with it. My readings showed that I've been having night hypos. Still, sometimes in the morning mismatch between FS Libra and a finger prick test is 2 whole mmol/l (and I've noticed that usually, the discrepancy between these 2 readings/tests is the least in the morning). I read that usually after night hypos you have a hangover effect when you wake up, which is not the case with me every time after such a reading. Is sensor "losing its power" the closer it is to the expiration? What's your experience with FreeStyle Libra?

So, unless your night time hypo is backed with a blood test, don't believe it. However, the libre results should at least suggest a good time for you to set an alarm and do a quick night time blood test....
 
I am pretty lucky with the readings I get from the Libre. VERY accurate. Some find them out a fair bit. Usually the last day or 2 I find the results tend to wander slightly higher in my case. Also you can get a "compression" low due to sleeping on the sensor and it will give you a false Lo reading. I have not had one of those as I place the sensor under my arm and not on th back side (of my arm). Never knocked it off on a door frame either

Everyone is different. I feel way better if I wake up low than high personally, but obviously either isn't good. Like others have said, it's possible the Libre is reading lower than you actually were. I also wouldn't worry if it's just a dip into the mid-high 3s and back. I don't think this is dangerous and in fact I think a lot of non-diabetics dip into the 3s so it might even be normal, but of course you have to know yourself and know if this puts you in danger or not.
 
Hi @nevenaves As others have said, don't trust a low reading unless it's been confirmed with a meter test, generally my libre reports lower results during the night, which was fun explaining to my consultant who queried the volume of hypos I was having during the night recently
 
Mine tend to read a bit low, some sensors more so than others, so I usually don't double check with my meter until Libre says I'm 3.5 or so. The sensors also seem to be a bit 'panicky' when going low and telling me I'm way lower than I am.

I test wit my meter a lot the first couple of days of a new sensor, to get to know it. After that it depends on how consistent the sensor is.
