230! It's a lot... If you are prone to it, than it's better to take care of it . Diet helps a lot. When I am watching my father-in-law and literally bitching about what he eats (I think he hates me sometimes! - maybe even more than I think
), his blood sugar falls to the safe 110. If not, it just shoots to 200th! Of coarse, your case is so much different, but still you need to help your body to cope in addition to the medication.
With best wishes,
