Well done on 12 days that's a great achievement!!. I know what you mean about it being very ingrained and it seeming strange not to drink at first, it will get easier with time I found it has for me, I am now at 8 and a half months. I was also a wine drinker and I always associated a meal out with wine for me they went hand in hand. Association is a very powerful thing and if you associate going for a meal with drinking, I really would consider not going.
You are early into your recovery, I definitely did not go anywhere near any place that would make me think of drinking or serve alcohol for many months. Could you not do an activity that you don't associate with drinking instead until you feel stronger?. When I was at that stage I would have found that very challenging and traumatic.
