No-one can convince me that short expiry dates on sensors are NOT an issue - the last one that failed had me super low, and then actually LO all day before it finally died and decided it wasn't even on my arm - and then yesterday and today my sensor has had me with very low readings and I am feeling fine. Well... as fine as one can be doing bills for the month, but you get my gist - no shaking, no feeling dopey (well... no more than usual). The ONLY thing this week since the low readings started was that the care home where my late mother was had a memorial service for all the residents who had passed away and I was able to make it at short notice. But as with all things where my moher's death is concerned, I have had really bad night's sleeps which on top of last week super jet-lagged coming back from Singapore, I am wide awake around 4:30-5am and I wonder if that somehow has had an impact? I just got a large glass of OJ from the bar, and and the levels seem to have perked up from 2.x to 4.x so the sensor is still working, of a sort. I have one spare, and was going to put in an order for 6 to take me through to the end of January and the first tournies of the year... so fingers crossed this is not on the way our, otherwise that will be a third sensor in four that has failed early - which is a little sobreing before trying to part with £300+ for an order of 6!
