fasting glucose in 70s

I was recently diangosed with LADA and have started injecting insulin in order to reduce really high postprandial blood glucose (often 300 mg/dL) in response to carbohydrates. My problem is that my fasting blood glucose is usually in the low 70s. This was an issue before I started on insulin last month. I always drift to somewhere between 72 and 75 mg/dL about two hours after eating (insulin or no insulin). This happens even if my postprandial blood glucose doesn't go higher than 105 (i.e., I don't eat carbs). If my postprandial glucose is high, then I can expect to go down into the 60s (sometimes 50s). I don't feel good when my blood sugar is anything below 80. Has anyone else had a problem with this?

My doctor says that 70-75 isn't that low and shouldn't affect the way that I feel. When I've had my non-diabetic friends measure their blood sugar a few hours after eating it's usually in the 90s. One night my blood sugar stayed at this level (90s) for a few hours (who knows why) and I felt good. As soon as I started feeling less clear headed I measured my glucose level and it was back in the 70s.

Any feedback on this would be greatly appreciated!

Re: fasting glucose in 70s

From what I understand and what's been told to me is, that your body gets so used to running at high sugars, that when it gets down to a "normal" level, (like the 70's) it feels as if it's running low because you've gotten so used to always being high. At least that's how it's explained to me. BTW, I too, get headaches and shaky when I'm in the 70's also.
