Thank you very much for your replies. I presume insulin resistance for type 1s would happen some time after the 'honeymoon' period ended. I know that many type 1s eat a healthy diet without limiting their carbs and inject to match the carbs consumed but Dr. Bernstein made a huge impact on my life and for some reason which doesn't make sense I'm frightened of insulin as well as carbs. Could partly be because one of my early childhood friends died from type 1. I cut my carbs way way back as soon as I was diagnosed but have tummy troubles if I go below 100 carbs/day, likely because before the diabetes diagnosis I very seldom ate meat. Anyway about a month ago my life changed. I returned to a busy job after 6 months 'retirement' and experienced a change in my blood sugar. I eat breakfast now and have 3 units rapid-acting insulin before that, 2 units rapid-acting before lunch (not much time to eat) and have increased my insulin dose before dinner to 5 units rapid-acting. I take 4 units long-lasting at night. I wondered whether the increase at dinner is due to my eating most of my daily food then whereas during 'retirement' eating was spread out during the day. Plus almost right after dinner I sleep for a least an hour - I used to have an afternoon nap. Or is the increase due to the end of the honeymoon, now that I have 8 months type 1 behind me? My blood sugars are good. My last Hba1c was only 4.2% which I think is 22 mmol (used a calculator but not sure). I know type 1 is for life but I'm aiming to stay at this level and not progress in anyway in order to avoid any complications.
