Well, up to 36 units a day now. The diabetic nurse said "I told you that you would not see much until 40 units" to which I explained she said "20 units"... but what the hell?!
My morning blood sugar is occasionally down to 10, but often 12 or 13 still. This is way better than 20 or so it was getting to at the start. So clearly things are happening. "Normal" is around 5 to 7.
I really felt a tad hypo today - having skipped breakfast - but the blood test said 10, which is far from hypo (it would have to be 5 or less to feel unwell normally).
So, keep going - keep upping the dose, and see how it goes.
The main thing is, over all, feeling better.
