@Molly M how did you feel? At 3 I would've been trembling, sweaty, heart racing etc, could your hands have been damp at all? Did you recheck it? xx
@Kaylz - my hands could have been damp as I had just washed them and assumed I had dried them OK but maybe I didn't - I assume that would have made a difference to the reading? I didn't think to do another test - if it happens again I will definitely do that.
At the time I felt totally fine, over the moon I had managed to do the walk I used to do (with only a couple of very brief stops) - then we had lunch and were both dropping off to sleep - I was no worse than OH (who isn't diabetic).
I will be checking my bg 2 hrs after dinner so in about 45mins time - hopefully that will be ok.
Thanks for your help @Kaylz
