I would also feel a bit of relief too Panache.
Know that from now on you will NEVER do or say anything you regret or feel ashamed of again as a result of drinking.
There will be no more opening your eyes and groaning trying to remember.
No mad dash to check your phone/email for what you wrote or who you rang etc.
As long as you don't pick up that first drink, you won't be getting drink again.
That must be something to smile about?!
It still makes me smile 402 days later!
