I am not strict on my intake but it's never usually over 12 n it's been 18-20 all his weekI am not on insulin, so I can't give you advice on that. Do you have high numbers despite eating low carb, or do you eat carbs? In the latter case, perhaps you could try cutting them and see what your numbers are. In the former, I would try for a dr's appointment - getting high bg readings without eating carbs signal that something isn't right.
