I think that is key. How many times have I drank over the fact that I was guilty I was drinking and sad at the consequences for my kids? Gah, this thing is just so insane.
For me, thinking in general is kind of the enemy. I just can't trust my thoughts anymore - they lead me astray again and again. I hope that this journey allows me to find and trust my inner voice again, but I'm not there yet. So I rely on others to guide me, and I don't drink today. Just today. Seems to me, lots and lots of "success" stories start with: "I don't know if I can do this forever, but I will not drink today".
