Hi Nuthead. You're obviously quite "sensitive" to your bg. Unfortunately I'm not (apart from a hypo of course). I get the surprise of my life if I've sunk down to 5 and the same thing when I've rocketed up to 10 as I feel no different. I always retest just in case, but usually only get a variation of about 0.5. I agree, it's a black art not a science. Wish this diabetic life could be a bit simpler.I always consider anything to do with diabetes control more of a black art than a science.BUT that's just my opinion...
I sort of have a 'feel' for what is going on with my bg . Also a good idea to retest is it looks dodgy. I have had similar readings that appear to be correct.
