Hi

Have a great time at your x-mas party and don't worry too much about what to eat. Do what you are comfortable with, there is always tomorrow.

As for the wine, personally I drink wine one night a week (Friday) and I always wake up to a loss. I am not encouraging it, because everyone is different, but I don't think it would hurt you to have a glass. Have a glass of a nice dry red wine. I prefer merlot. Keep in mind you are low-carbing and trying to lose weight and get healthier, you are not giving up all the fun things in life and if you want to kick up your heels and have a glass of wine at a x-mas party I say "Go for it"
