Bonking without meds or exercise

Well, I had an early afternoon crash (low blood glucose) today. That's without taking any metformin in the morning. My BG reading was 86, which is considered a non-diabetic fasting blood glucose level. Normal fasting blood glucose typically ranges from 70 to 110 mg/dl. So I didn't take metformin (normal dose 250 – 500mg in a.m when I am not running). I did have a couple of pieces of toast with black raspberry preserves (no sugar added) and a piece of cheese. So what caused this low? My guess is that my 5 mile run yesterday and massage had an impact, as well as the fact that I continue to take glimepiride, a sulfonyurea, which is an oral med that induces the body to produce more insulin. I typically take it with the evening meal, though the normal recommendation is with morning meals. When I was taking it with morning meals, I was getting low blood sugar readings by early afternoon.




My next step in self-experimentation is to take glimepiride out of the medication line-up and see what effect it has on my morning fasting glucose levels. I have been consistently under 100. My last Hb A1C (Glycosylated Hemoglobin – a measurement giving a picture of glucose control over a three month period) was 6.5 which is the upper limit of normal.
