I have dropped down to around 30 gm per day when I was trying to keep my BG levels down below 8 mmol in the evening - not every day, but three or four times in a week. It seemed to give me the push I needed and even though I increased carbs again I now see lower numbers. I have decreased carbs this week in the hope of losing weight - now that I respond to insulin by storing fat I have to try harder to lose anything - in fact I had put on a couple of pounds last time I weighed, which was always very easy for me to do.
