Well I haven't as yet been on a DAFNE course so here's my view on all this.............
As some might know, I became type 1 in 1965 when I was 10 years old. I went into hospital for about a week and was lucky to be stabilised on one injection per day of Allen & Hanbury's Lente (beef) insulin. It was explained to myself and my mum that I would need to keep to eating a set amount of carb at specific times of the day in order to balance out the effect of the insulin. I was shown how to inject, how to test my urine, what a hypo would feel like.....

The nursing staff made a real big fuss of me.
While in hospital I wrote down in a diary all the meals that I eat and noted the portion sizes of potatoes etc. For about a month after I came home my mum just carried on cooking exactly the same portions of food as I eat in hospital. It was only when contact was made with the British Diabetic Association (now DUK) that my mum found out loads of info about the carb value of food, and using the 10gram exchange system so that I could eat more or less anything as long as it equalled the amount of carb that I was due to eat for each meal. The BDA were brilliant. I was however only eating 100 grams per day of carb and after two years looked like a stick insect as the carb allowance was not really high enough to enable me to put on any weight. It was only when my mum sought advice from the BDA that we had a row with a junior doctor at the diabetic clinic about the restriction on carb and he agreed that I was too thin for my age so increased my insulin dose and my carb intake upto 130 grams per day. From then on I always knew what effect carb would have on weight so just did my own thing as I got older.
It is now 44 years on lol and although I have gone from one injection, then to two, and now MDI, I still eat the same way more or less as I did years ago. However, I have of course altered the amount of carb that I eat so as to keep my weight ok but still balance myself with insulin and carb by eating little and often. It's been fairly easy peasy really, I'm not one for making life too hard for myself.
I have learned through trial and error how to calculate my insulin bolus and can just eyeball food to roughley work out how much insulin I need to use and do bg tests about 5-6 times a day so that I can alter if need be, the amount of carb that I eat as a snack. No one has ever suggested to me to look at insulin to carb ratios.
Since moving address two years ago, I have only seen a consultant once. He congratulated me on the number of bg tests I did and said that he had a job in getting people to do any at all. I asked if there was anything he could offer in advice to me and he said that only I could look after myself with diabetes and that if I carried on the same way I should remain complication free.
My hba1c ranges between 6.4 to 6.7 since testing 5-6 times a day and touch wood :wink: , I haven't as yet come unstuck so am fairly happy.
