Thank you @Bigbus :-)
I think my success this time has been because I'm ready. I've spent years getting more and more entrenched in the drinking habit - the social circle and work drinking culture and mummy 'wine o'clock' just made me see it as inevitable.
Plus I was 'only' drinking 3 or 4 nights a week, 1 bottle of wine (plus a glass or two from a second bottle if with my husband) that I normalised it. I ignored the multiple wines every day on holiday, christmas, any excuse for a celebration.
I had numerous half arsed attempts at moderating, at dry Jan, at only on weekends, at never at home, which of course lasted only a matter of days, before finally getting to the emotional point that my drinking wasn't adding to my life.
That's why I've quit all together, which has felt easy it's time. Moderating just is too hard for me - it would be like being a heavy smoker and trying to only smoke on a Friday and Saturday night.
Also, deciding to quit altogether has meant I'm really enjoying seeing the small changes happen in my thoughts, energy and outlook on life, rather than white-knuckling through to when I'm 'allowed' to be 'normal' with wine. I didn't learn anything about myself that way, other than that I could sometimes power through if there was an end in sight.
These threads have helped me enormously :-)
