I'm a little concerned about the work Christmas party on Friday. My boss has arranged a wonderful celebration spread over 12 hours. However, since having my daughters I have lived an almost tee total existence, having a couple of glasses of wine with a meal to mark a special occasion and nothing more.

I'm worried I will over indulge. Not fab!

My usual technique of sipping from the same glass all night will not work in such a small group.

Do you have any tips for remaining sober during a night of excess?
