@porl69 I eat what I want and bolus for the carb intake.
I'd like to do the "if I get it wrong then I remember for the next time..." thing. Unfortunately, I get bored with food very quickly so eat variety. I can't even cope with the same thing for breakfast more than two days running (toast one day, yoghurt the next, eggs the next, cereal bar as I run for the train the next, fruit the next, ...). As a result, by the time I eat the same dish again, I'm back to the drawing board calculating my bolus requirements. Thankfully, they are mostly correct and I test regularly for correction doses.
The dietician once told me I needed to remember no more than 10 meals because that's all the average person eats - that's less than half a week for me! I probably eat getting on for 50 different meals in a month.
