First , let's change the way we look at the holidays and parties we attend. This is a good way for anyone who is trying to stay on any diet to think about these situations. Just keep repeating this to yourself. You will meet new and interesting people with whom to talk. The festive atmosphere will make the evening memorable, not just the food.
Friends are more important than food.
Second , let's plan ahead. This is very important. If you don't know how to change your meals and snack times, and mesh that with your medications, talk to your doctor or diabetic educator. Get information on how to regain control of your blood glucose levels if you overeat, or eat something that looks innocuous which turns out to blow the top off of a carbohydrate chart or glycemic index. Be honest with yourself.
