Welcome Amanda - for sure the first days and weeks are the hardest. And for me, grieving the loss of alcohol was a real phenomenon. Rather than focus on missing it, though, I had to find fulfilling actions to take instead. AA meetings and individual counseling fit the bill for me - they helped fill my day, reinforced my sobriety and got my mind into a much more positive attitude regarding the booze.
Blessings on your house as you begin your journey!
