I use CalorieKing I am a vegan so I make most of my food. I do not do exact weights etc, I just get close.
So I would look up a large carrot (7), look up a sweet potato (20), look on the package of tofu (5), The green leafy stuff I don't count and a cup of non starchy veggies for me is about 5 carbs. So the tomato, cucumber, mushrooms, broccoli in the cup of this on my salad is 5 carbs. Dressing in my case 0 carbs.equals (32) carbs, in my case I will eat half which equals 16 carbs
But look it up once, the carrots, onions, sweet corn, peas, add it all together and divide it, if you eat half, by half, if you eat a third divide it by a third. Plus for commonly used foods you start to memorize the carb counts for them.
Keep the "recipe" in your diary so you only have to add it up once. and if you make a substitution say the carrots for zucchini you can just make a note at the bottom at the bottom of the page less 7 carbs for the carrot add 3 carbs for the zucchini type of thing.
I can't give advice on your ratios of insulin, we're not allowed, but I suggest you ask to be taught how to learn to either decide that or what information your team needs to judge what you should be taking.
What did you do before Daphne that worked so well? You might need to revert to that.
