Grrrr. HbA1c gone from 40 to 42. No apparent reason. Good adherence to low carb. Could go lower still I suppose. Need to have a long think, but this is the first measurable backwards step in my T2 experience. Not a big backwards step but not one I can ignore. Feeling a bit downhearted and grumpy about it. Doctor wants me back on Metformin but I feel it's too early for that. Harummph.
