How many carbs does it say on the package?
Are you carb counting to determine your doses of mealtime insulin? If so, count the carbs and dose according to your ratio.
If not, what insulin regime are you following? How are your blood sugars doing with your cold?
It's different for different people, and the difference between people can be so large that any advice on what you should take would be dangerous medical advice.
Can you contact your diabetes team for guidance?
Hope you'll feel better soon!
