Hi, I dont know if is helpful. But in my case, last year I saw a bigger increase in my NovoRapid requirements ie:- If I had 40 carbs I would have to take 6 or 7 units.
I have Coeliac disease, but maybe a long time before diagnosis , I had maybe 1 unit for breakfast, niormal 1 unit to 10 carbs for lunch, but dinner was 3/4 's of the full amount ( 60 carbs and only 4 units) bedtime Levemir was 16, then 14, last year 12, and now 11, but NovoRapid has really increased..
I have been thinking on the lines of Insulin resistance ? or last year many upsets, stress, worry and health problems ? ha that affected me ? like you I am a little confused at times.
I have never eaten snacks in between meals and my weight is about 120 lbs. I cant eat foods without taking Insulin and I've always been like that.
Maybe we could find out together ? Good luck
Take care RRB
