Good for you! The more times you can keep from injuring yourself, the more strength you gain and the less power the urges have.
Be careful with the alcohol. Make sure that you aren't just trading one destructive coping mechanism for another. One shot isn't a big deal, but those of us who are or have been cutters know that it is an addiction. If you can become addicted to one thing, you may have an addictive personality.

I can't tell you if the urges ever go away, but for me, they have gotten much weaker. My last episode was two years ago, now almost three, and when I feel the urge, I know there is something really bothering me and try to figure out what it is and what I can do about it.
