Maybe you could devote the day to giving your body birthday presents - delicious healthy food, a hot bath, a massage, fancy expensive juice that you would normally pass by...
No matter what we've done to our bodies with our addictions and/or alcoholism, if we are still here & alive it means our bodies are serving us like valiant warriors.
Make it a celebration of your indomitable and brave body, which just hung on through a whole nother year!!
