Good job!
I'm coming up on a week again, which is where I stumbled last time. My AV is definitely starting to try and convince me that we've made it long enough and should celebrate, but I think this time I'll win the battle. Even just 1 drink makes you feel miserable and like a big disappointment the next day! Not worth starting all over again.
The lock sounds like a great idea! No need to tempt yourself right now with access to all that booze.
