I haven't self harmed in about 8 months now - before that I had 18 months, but I still think about it all the time. Things that helped me quit and help me get through the urges were drawing on myself with a pen (incidentally when I was in a psych hospital this summer if you told the nurses that you wanted to si, this was one of their suggested alternatives), distractions, writing - even if it was just stream of consciousness ranting, and getting out of the house away from my tools and doing some exercise until the urge passed. I also found it helped once I started to consciously try to figure out what emotion was behind the urge, ie was I angry, sad, wanting to feel real, wanting to feel numb, because then I could come up with alternatives that met that emotional need.

Good luck.
