Welcome to the forum
@MichelleF78
I feel your frustration!
Yes it’s not ideal having to double guess how meals out will respond, and how to dose for them appropriately for you (including any splits, and how far apart those need to be). Nothing like when the only problem was deciding which of the lovely things you fancied most!
But…
On the plus side, give yourself
HUGE credit for the amazing learning you have already picked up. Some don’t venture into the world of ratios, split doses and those sorts of techniques for years or even decades
Plus…
You are still on that pretty steep learning curve. So you have to commit to quite a bit of trial, and accept a reasonable degree of error. Which means you
have to eat out at pizza restaurants A LOT. For Research.
Otherwise how can you expect to gather sufficient data??
😛
For what it’s worth, like
@SB2015 I also tend to find those larger-than-normal meals are more art than science. I seem to need a different meal ratio when the carb load goes over a certain point. And I’ve got to a point now where I can just guess the amount of insulin I generally need by the time I get full and can dose that without particularly having to attempt too much in the way of Diabetes Maths.
And
mostly, that works out very acceptably well. Sometimes spookily so!
Good luck with your selfless ongoing experiments.
