Hi pink panther
I have been T2 for 8 years and on oral meds until I had an illness 18 months ago and since then have been on humalog x 2 daily. Originally on 6 units x 2 daily but it increased over the months to one point where it was 24 units x 2 daily. I also started taking metformin and have now reduced to 16 units x 2 daily plus 2 metformin x 2 daily.
My diabetic nurse checks with me on a monthly basis and I have changed my diet to a low GI one and it has helped reduce my blood sugars.
Have you taken advice from the medics cos it seems that it might be a good idea for them to help sort out why your HBa1c is increasing.
Good luck
