Ah, ok
Thanks for clarifying that.
I think the first Xmas with diabetes IS hard. Rightly or wrongly, Xmas is seen as, basically, a time to stuff your face to some extent! Even the special Xmas foods tend towards high carb eg cake, pudding and mince pies.
What I do is plan alternative treats eg I buy some nice smoked salmon and cheeses because they're tasty but no carb. Turkey and posh ham are good too. I also buy some nice wines. I plan out the meals so I know I won't feel deprived but, on the other hand, won't end up with high sugars that make me feel bad.
I do have say, a mince pie, a small helping of pudding, a little slice of cake, etc but I space them out, have insulin to cover them, and, if possible time them so I can get some exercise after. For example, a nice long walk means I can have a good size piece of cake with little or no insulin.
I think the key is planning what to buy and what you'll be eating on the special days. It's also important for your husband to do plenty of blood tests as the extra sitting around as well as the food can put sugars up.
Get sugar free drinks and mixers. Maybe choose low carb nibbles rather than carby ones eg those preprepared salmon mousse rolls, mini peppers stuffed with cream cheese, etc. Even things like biscuits for cheese can vary in carbs quite a lot, so choose carefully.
I enjoy my Xmas
Please tell your husband it doesn't have to be rubbish and miserable. He can still have a nice time
