In all the years I've done SW, I have never changed my Christmas dinner. I've always eaten and drank what I wanted on the day. Partly because we aren't always at the same house each year (mum and auntie take turns each year) and I can't ask someone else to cook everything in a special way just for me, but also because I don't actually cook it lol.
I do make wiser choices with things, like I stick to spirits rather than wine or beer, and I don't gorge myself on the crisps, cake, sweets, chocolate and god knows what else like I used to.
And I don't leave it until new year to get back on plan. Or I won't be this year at least. I'm allowing myself Christmas Day, and some goodies on Boxing Day (not all bad stuff though!) and maybe New Year if I actually make any plans. Last year me and mum vegged in front of the TV and had a bottle of wine and that was it!
But every other day before and after Christmas Day will be all on plan
