All I can say is... hang in there. You're doing an excellent job reducing carbs. And numbers frustratingly seem to plateau after an initial drop. And then it creeps at snail's pace downwards. But that has taken me months to get down to this point, and it took weeks when I first started this no carb thing a few years ago. We seem to be on a similar journey....I'm currently working on lowering HBA1c taken in April of 88. I've been up and down this road a few times though. I tend to yo-yo with food and increase carbs (majorly) when bad things happen in life. I know what to do... but don't always do it, obviously. My app now says I'm at 59.8, with numbers similar to yours above. I cheered this morning when I got 7.8 as my morning reading... it's dropped 6 points over a month. What you're feeling does sound like Keto flu. I saw my first number below 6 for quite a while a few days ago... all of these things are wins! It's so exciting when you see a lower number than you were expecting!
