Would it help to have a start date in mind, rather than trying to give up now with Christmas round the corner. It must be a bit like turning vegetarian once someone puts a delicious bacon butty in front of you.
I can't really advise because I haven't given up drinking, I have cut down a lot in recent years and reasonably successfully moderate.
But if I were you and trying to make a go of giving up for good, I would start on January 1st and do 'Dry January' - you can hide amongst everyone else who is doing it for both inspiration and support, and if you don't want to make a big thing of it with family and friends, by telling them you are doing Dry January the spotlight won't be on you.
Four weeks alcohol free is a good platform to then continue.
Read Alan Carr and Jason vale both in the meantime, as they advise carrying on drinking to the end of the books, which might coincide with a January 1st timescale, and those books may be the inspiration you need.
You might think that's all bollocks coming from someone who hasn't stopped drinking, so sorry if you do, it's just an idea.
There is also a forum called brighteyescouncelling I take a look at from time to time which you can join and do progressive challenges 7 day alcohol free, two weeks and so on.
I go for the odd month alcohol free myself and I'm planning a Dry January; and considering signing up to Belles 'tired of thinking about drinking' 100 day challenge. I did sign up and she contacted me to start but I chickened out and deferred it! I feel fairly confident I'm going to give it a go in 2015.
Good luck with whatever you do.
