don’t fret, I’m a T1 for 51 years and I’m still rebalancing my ratios. I generally have a 1:7 insulin/carb ratio, but throughout the morning, it’s a 1:6.8 until about 11 am. I also have a higher basal limit around dawn (1.0/hr from 6 to 11 am), ask your doc and CDE to explain dawn affect to you. With your pump, you should be splitting your injected insulin between basal and bolus, right? Also try the dual/square settings for meals. Take your meal bolus and split it so you get half immediately and the rest in 30 or 60 minutes, more like how a pancreas releases insulin as glucose levels rise after a meal. You may see your post prandial levels not shoot up so high. And btw, going up to 200 after a meal is ok a long as it doesn’t stay that way. I’d it does, you either need more bolus or basal.
Cherry is right, keep a food log for a few weeks. Time, what Food, number carbs, pre and post meal (2hr) glucose levels. After looking at the patterns, you’ll figure out the right levels for you! And then you’ll have to change again!
Good luck- feel free to message me for more of my experience
