Today is a good example of why I am so baffled by my high sugars all week:
Friday means I have a cooked breakfast from the work's canteen, this consists always of 1 slice of toast, 1 slice of bacon, 1 fried egg and 1 hash brown. I count this as being 40g of carbs as an educated guess. So using a ratio of 1 unit:4g (sorry I got it wrong on my original post, this is because I actually see it as 2.5 units:10g) I take 10 units of novorapid.
Pre-meal reading was 9.2, took novorapid 15 mins before eating, 2 hrs later my blood sugar was 8.2! Such a relief after feeling so rubbish all week!
I really think it's the mixed nuts & raisins that are messing everything up. I don't know why but it's as if the insulin just can't touch it.
