DV,
Try to think of your "crappy day" as a step closer to having really good ones. That's what I did. Baby steps at first. I also got somewhat angry at times and would say "hey bring it on I can handle it". "You won't beat me this time." (meaning the alcohol) "I'm stronger than you." Kinda recondition your mind.
When the urges come (and they will) to drink or use call them out for what they are! Liars!! Trying to pull you back to that horrible place called hell. I'd dismiss them, laugh at them even! Wouldn't let them win. You can do the same DV see if it helps.
Take care, I'm very proud of you! :ghug3
