Hmmmmmm. As you would expect, I have a couple of observations. But, do tell me to get lost if I'm interfering, but aren't other peoples situations much easier to interpret and manage than our own?
Your latest A1c score converts to an average finger prick reading of 6.4. (
http://www.diabetes.co.uk/hba1c-to-blood-sugar-level-converter.html), so if your fasting averages 6.6, then you are also having significant periods lower than this. Have you tried any focused activity to lower your fasting levels? I was fortunate an oughtn't to have struggled with this, although I only started testing my fasting a little while after diagnosis. My initial approach was to not ignore fasting, but to concentrate on the readings I could easily influence; i.e. those before and after I have eaten. Then I started looking at my fasting levels. Was this correct? Who knows, but it sort of worked for me.
Have you discussed your fasting levels with the doctor you appear to have been able to trust, or at he hospital? Are your other scores noticing down at all, or is your improved score reflecting fewer peaks, following questionable food choices? Could it be worth revisiting the Dawn Phenomenonenonenon thread, and perhaps experiment a little with a modest snack
Each time we correspond about fasting bloods, I have an outlier. But, this morning, I have my highest in a long time, at 4.6.
Stick with it Scandi, but going to 2.6 can't be the greatest thing to do. Your profile suggests you're on 2 Metformin doses a day; could you reduce that to one, taken in the evening, in an attempt to maintain the benefits, and time the benefit to impact your fasting scores?
It's all a puzzle.
