I know what you mean about Christmas eating. I have had 2 office parties, managed to ignore 3 bake sales at work, have to face an open house on the 24th, host dinner on the 25th and 26th and then I'm hosting a video game night on the 29th - I'll be drinking mineral water and eating celery on New Year's Eve!
At least I'm hosting most of the events so I can control the type of food being served and maybe be I'll too busy playing hostess and I'll forget to eat.
My only real problem will be the wine.
It sounds like that Slim in 6 is working for you.
Do you just do the exercises or do you follow the eating plan too?
BTW - I am glad that your friend is progressing - hope things continue in an upward mode for her.
