There are figures that the gp expects on your blood sugar test as a diabetic at your stage of kidney disease. Mine were 74 in June after I had had a cold for a month. Figures on blood test say 49 to 90 as reference point but 120 up to 150 max is used for non diabetics I think. I used to have 100 to 120 five years ago but moved house and don't get as much sleep these days due to neighbouring tenants. The lower the creatinine level goes, the more tired you feel.
My platelets count was 165 at the time and I had a nasty small spray of blood at work when testing my blood sugar.
