We made some of our regular treats and some "bariatric" friendly treats as well, but I am approaching everything with moderation. We aren't going to alter things too much, especially as this year seems to need some good holiday cheer, and if that involves a few treats/drinks, I'm going to have my small amounts and enjoy it.
It can be a challenge sometimes, but given that we are pretty much staying at home, we have control of the environment, so that helps.
Don't be afraid to treat yourself a little bit, but commit to getting back to normal, healthy food immediately after the holiday.
