That's quite some achievement Biggles - hope you did indulge in a sober treat or two :)
Had my DTs birthday party yesterday. The entire experience fuelled entirely without alcohol. Realised that there's no getting round it, kids parties are horrifically stressful. But at least this time I wasn't lurching between panic at what lay ahead, deciding that wine will help, and then having the same panic afterwards but with a sore head on top of everything else. The party was a huge success, and alcohol would not have stopped the sound of 26 hyper, Frozen-enthralled children being mind-bogglingly awful to endure 
Had my brother and family here afterwards yesterday, and ended up having to explain to a very confused SIL that my decision to stop drinking is not just a temporary 'weight loss' choice but something I want to do permanently.
Lucy - I saw that article, all very familiar, thank you. I never really thought of myself as a massive Christmas drinker, but I am processing a lot of thoughts at the moment about socialising without booze in general. I must pop over to the Christmas thread too.
