Binging and over eating on the holidays!

Don't wait until dinner time, have a good breakfast with protein, do your workout if you can, and try to eat only veggies and lean protein, and of course the treat is my red wine

Similar situation as OP. Way I personally take it is to just do it one day at a time. Yes, over the weekend I went over my calorie goal. But don't beat yourself up over it. That day is past, you can only concentrate on the present and don't worry about the future, it will be the present soon enough and you can worry about it then. Just concentrate on staying within your goals for TODAY and tomorrow do the same thing and the day after etc. That's really the only way I can recommend getting back on track.
As far as working out goes, just remember why you are doing it, find the reason that motivates you. Where I'm at it rained during the morning and was damp and humid for the rest of the day. I really did not want to go work out. But I did, because its just about today. I think to myself "I'll regret not having gone. But I'd much rather just sit at my PC." So I make a compromise. Go, workout, and afterwards I can get on here while feeling good about it.
So I guess the way I handle it is don't stress the past, you can't change it. Take proactive action for the present and occupy yourself with that. And don't sweat about tomorrow, it'll come soon enough.
Stay strong and meet your goals.
