Its interesting how quickly one starts to think - well nothing much I am eating is affecting it so maybe I could save money by using it intermittently.
However for me, the sensor acts as a permanent reminder not to open the fridge door because now it sitting there I know that I will be stuck with looking at the consequences of that action for weeks to come. That is especially true of the later night snack, like now , my blood sugar is 4.7 , if I don't eat anything it will stay around there all night and tomorrow will be a good day. If I have a snack, then my fasting blood sugar will be at least 1 mmol higher and tomorrow will be the worst day for a week!
I know it is the thing that has kept me trying to diet, despite it being so hard to shift weight recently, because if I eat much the blood sugars go up to. I think it has been that which has kept my weight stable for the last couple of months My suspicion is that the monitor is going to be permanent. like having a little angel whispering in my ear 24/7
