Since the stroke I've been very disciplined in measuring my sugar every morning before I eat anything. The numbers themselves, though, aren't quite as impressive.
When I was first diagnosed as diabetic, 20 years ago, my sugar would always be in the range 6-8 (mmol/l), which really is quite indistinguishable from somebody living without diabetes at all. There then followed a period where I didn't really measure myself, until the stroke. By definition, levels leading up to the stroke are far harder to know, although at one point in hospital just afterwards my sugar was over 30! (caused not even a half dozen Mars bars, but by white bread which I avoid since) Everybody got very worried, and the doctors put me on an insulin drip for the next twelve hours.
Anyway, after that scare my blood sugar is under far better control, but clearly I have damaged my pancreas. The result is daily readings, generally of between 10-15 mmol/l. Under 10 is good.
I'm obviously very careful with what I eat now, but there is room for, say, a slice of cake here and there. There is a definite link between the carbs I eat, and my sugar. Exercise also comes into it, although the link between the three - I can't tightly define it.
I got up yesterday and measured my sugar at 15. This is very much at the upper end of the scale regarding what I regard as acceptable. So it was a frugal day.
Just to give an idea, yesterday's menu comprised:
breakfast - porridge (oats, water & milk),
lunch - 2 x mini pork pies,
late afternoon - 1 x mini pork pie (they come in packs of 6),
supper - ½lb high-meat-content pork sausages (no carbs or veg yesterday) plus a low-sugar yoghurt
and that was it. Apart from the observation that I'll soon look like a pig, no snacks, apart from the one mentioned, whatsoever. And, a ward drop-in to boot, so probably a mile's walking to and from the bus stop. Tea, of course (I drink it by the gallon these days), but although I have it with a dash of milk, there are very few carbs being consumed.
The end result of all this was a sugar reading this morning of 6.9, which by my standards is very impressive, probably the lowest since the stroke (and bear in mind that there is now a dataset of hundreds of daily measurements). I was quite anxious, I really hoped it would go back down on its own, I really don't want to end up just taking more and more insulin (until?) So I feel able to relax a little today, as evidenced by the two muffins I just had for breakfast. Roll on tomorrow!
