Carb ratios

I found my original carb ratios were too high and my bloods weren't lowering for hours after eating, I've adjusted them for different times of the day, i.e. lower carb ratios for breakfast and lunch but higher in the evening and they're working really well but my DN isn't happy - she feels I should be on a standard carb ratio through the day. Can I ask what others do please?

Thank you, that's just what I wanted to know
