So I have just looked back at my readings from December on the mySugr app:
Day 1 : high 14.9, low 12.6
Day 2 : high 16.3, low 9.7
Day 3 : high 11.9, low 8.9
Day 4 : high 10.1, low 5.8
Day 5 : high 11.2, low 7.6
Day 6 : high 10.1, low 6.5
Day 7 : high 8.0, low 5.6
And one month from diagnosis, high 6.4, low 5.9 and pretty much between around 4.5 and 7.0 ever since, my 3-month hba1c was around 35.
Of course during the first few weeks I was furiously testing and trialling foods some of which really didn’t work for me (bread, I’m looking at you!), which lead to some spiking. I was ramping up my metformin dose for the first couple of weeks as well, but as you can see, I found that the BG readings were really responsive to what I ate. I still get a higher fasting reading in the morning though, still early days for that to come down, but it doesn’t seem to affect my hba1c.
