Key, happy to hear you made it through the family gathering. It still amazes me when I think about how many dysfunctional families there are. These early months can be a real challenge but just remember that it really does get easier - in my case it was gradually over time. As someone else posted, we learn to strengthen and flex our sober muscles.
Amp, a plan is always good! I still do a quick mental check before I go anywhere there might be alcohol. I expect that will be a long-term process for me.
The holidays are, I think, the roughest time for most of us. We'll get through them together!
