Hi
@type1newbe ,
Nobody will know the correct dose for your meal, and we definitely can't give you dosing advice.
How much insulin different people will need for the same meal varies highly, some of us will only need 1 unit for this meal, others will need 80 units.
You usually use 8 units of insulin for your meal, how does this meal differ from your usual meals? This may be a start in working out if you need more or less than your usual dose.
How are you currently deciding on how much insulin to take for your meals? Are you calculating carbs and adjusting your doses based on that or are you using a fixed amount of insulin?
A possibility for this meal is check BG after the main course, and skip dessert if already rising quickly, especially if you usually don't eat sweet desserts.
What I often do to keep things easier to manage is to only have a single bite of dessert for flavour.
I think the main thing is to log how much insulin you've had, and how the meal affected your numbers during the 4 hours after.
This will give you a better idea on how much insulin you may need next time you'll have a similar meal.
Good luck!
