I so agree with Dee, Aussie. We're not weak, and sobriety isn't about willpower. In fact, I'll bet alcoholics are some of the strongest people out there. We have to be simply to SURVIVE.
One of the most powerful quotes I've heard is this: I'm not a bad person who needs to get "good" ... I'm a sick person who needs to get well. That really resonates with me. I'd always seen my addiction as a personal moral failing, and I couldn't figure out why my faith and my character couldn't save me. I wasn't adding the physical component. I am sick. When I drink alcohol, I forsake my sanity and am incapable of making good choices. I can avoid the worst symptoms of my disease as long as I avoid the catalyst, which is alcohol.
Rest it off, and start again when you wake up.
