Hi - spooky as I was just about to ask a similar question when I saw yours. I have been testing for a week now and twice I have had very different readings when using the meter just 60 seconds apart. On the first occasion I got a reading after eating of 8.3 - literally 60 seconds later it was 6.8. Tonight the first reading was 8.7 the 2nd 7,4. Is this usual? I used the same finger for all readings. Also on the 2nd readings there was only a difference of 1.0 on the pre meal readings - can I take this to mean that what I ate tonight didn't cause a spike?
