Doses are very different from person to person! There must be some underlying biological reason, as well as - of course - amount of exercise/ food etc.
Mike, out of interest, how much short acting do you take each day? And how many times do you test your blood on average? (Actually, that one's to you too, Katie!)
welll... Usually for breakfast I have 30g of carbs (weetabix) and I know from experience I need about 8 units for it. Lunch usually another 4-10 units (now that im low carbing, used to be more like 14, 16, 20 etc). Dinner about the same as lunch. And probably about 10 units in snacks if im being bad! more if im being very bad. Hmm, I might try writing it down for a few days because that's probably way out!
They are going to start making insulin pens with memory so that your consultants can check up on you and see how many injections you are doing & how much. That would be useful 🙂
