I'm onto Day 3 and something that is helping me from being so scared is to only think of not drinking in segments of 24 hours or less. I went to my first AA meeting yesterday and they gave me the book "Living Sober" and I thought it would be redundant and not helpful and it has been so enlightening. When I think in terms of "Never again will I drink" and "I'll never taste another drop of alcohol again" it can feel scary and overwhelming. But taking it a day at a time, literally, and just filling up that day with activities is helping me through this initial adjustment.
Hang in there!
You rock and we're all in this together!
