Yes, she'd eaten not long before that test - she went up a bit then came right back down! It does make me wonder if she might have gone under the 50 yesterday afternoon while there was no-one here to test but Michael had to go into work for a couple of meetings so there wasn't anything we could do about it. And we weren't expecting her to be that low after the earlier readings he'd got before he left either!! I think you're right - she's so close to being done with this dose, but she's just not quite there yet!
Michael will be home all day today fortunately - I've asked him to get a couple of extra tests to make sure she isn't about to have a mid-afternoon low so he'll be about to deal with anything like that if it's before I can get home.
