First christmas as a diabetic

When I was first diagnosed I was told not to take insulin for alcohol but it’s my first christmas as a diabetic and this comes with some new types of alcohol like mulled wine, buck’s fizz and eggnog. I’m having a christmas day with my friends tomorrow and wondered if I need to take insulin for any of these? I tried mulled wine last week and it made me go quite high but I came back down. Ive not had buck’s fizz or eggnog yet.

Any tips for drinking it? Both if I have just a glass or end up having more?

Also any other christmas time tips would be useful!! It’s a time that really focuses around food so its making me quite nervous
