I have evolved to eating about 70-80g of carbohydrate per day in an attempt to gain better control. I didn't make a sudden decision to cut back, more of a gradual change. When faced with serious complications of sight loss, kidney disease and no hypo awareness plus advice from the clinic to get my HbA1c down towards 6.5 it seemed like my choices were limited.
The only safe way I have found to get my HbA1c to 6.6% is by reducing carbs and consequently reducing my insulin requirements. I'm in the tricky position of having no hypo awareness where you would aim for a slightly higher HbA1c but having complications where I need as good an HbA1c as possible. Getting to an HbA1c in the mid 6's although it has been quite a challenge is where I need to be for my future well being.
My diabetes tightrope has become narrower and narrower to balance on with less wiggle room. A lower carb diet has seemed to help me balance a lot better whilst thankfully avoiding too many hypos. My choice to reduce my carbohydrate intake and insulin needs was met with raised eyebrows at my clinic although they were pleased with the resultant reduction in HbA1c
