Had an appointment with the diabetic consultant in the week, and they've referred me to have a constant monitor fitted. I thought my blood sugars were doing ok, but he told me that the levels I'm getting in the mornings are what would be classed as high for a healthy person.
It sounds bad, that my diabetes isn't as controlled as I thought, but he said that the high sugar levels could explain my increased ADHD symptoms. If that's the case, this should help me get them under control, and bring my forgetfulness and brain fog back under control too. I'll take that as a potential win for now :)
