@teloz – it’s not *that* bad surely? I started simple, with a 1:10 ratio – so 70 grams of carbs equals 7 units of insulin (I find carb portions too confusing – I’m quite simple).
Once you’ve got that roughly sorted you can start experimenting with adjusting the ratio depending on the time of day – I do about 1:6 in the morning 1:8 in the middle of the day and 1:10 in the evening. The critical thing is to experiment and note down **everything**!
