Thanks all - you've given me a lot to think about and a great deal of heartwarming support in the 30 minutes we've known each other! I'll keep you posted on the 28 day thing and then I'll have to make a decision.
Must say it was strange - not necesarily bad - not to be drinking on Friday/Saturday/Sunday nights - this is big style family time for us with lots of food, wine, wrestling with the kids, etc. It was fine, but the thought of not drinking ever again is an interesting one. How do you negotiate Christmas and New Year, for example?
